Tech to Amplify Rather than Atrophy


I just finished Matt Crawford's latest book, Why We Drive.  This challenging read unpacks how we've backed ourselves into an intellectual dead end under tech driven surveillance capitalism.  Crawford comes at it from the big-tech push to colonize one of the last moments in our lives where human skill is tested and judged by reality rather than marketing expectations, vehicular operations.  Advertising companies like Google aren't trotting out self-driving cars for safety or efficiency (though that's the marketing), they're trotting them out so they can take all that consumer attention wasted on driving and advertise to it.  Even with this problematic impetus and misleadingly media spin self-driving vehicles are imminent and this leads Crawford to (quite rightly) question the intent of the companies pushing them.  The assumption that self-driving cars will somehow be  better for us is undressed in many ways in the book.


Seeing where Matt's head is at in 2020 encouraged me to reread his first book, the bestselling Shop Class as Soulcraft, which came out in 2009 in response to the market crash that everyone seems to have forgotten now as we're increasingly told we need austerity to pay back the predatory organizations who caused the debt in the first place. Running the economy is a good gig if you're one of the 'financial class' who maintain the fiction.  You can crash the market and make billions of people poorer and then profit from it indefinitely as you charge interest on the loans you handed out to 'solve' the crisis you caused.  It takes a special kind of stupid to buy into this.


Looking at Shop Class now years later it has historical context to it I didn't see in earlier readings where the response to the market collapse wasn't as obvious.  Back then it was just timely.  One of the themes that follows Matt's thinking through all three of his books is his dislike of automation.  In Shop Class he talks about situated knowledge and the importance of having an intimate relationship with reality.  Fundamentally, Crawford believes this vital to human beings fully developing their abilities.  When we're devalued by monied interests into simplistic consumers we are unable to fully develop our human potential.  Surveillance Capitalists intent on monetizing every moment of everyone's existence for their own financial advantage have coupled with safety and efficiency movements in government and society to create a brave new world of atrophied people.

I've come at this digital prejudice from an educational technology point of view on Dusty World, but it bears examining from a motorcycling perspective too.  Crawford is a physicist and mechanical and electrical technician, but he seems to have drawn a hard line between digital technology and everything else.  It's probably an age related thing.  Matt's about five years older than I am.  As I was getting into early home computers and figuring them out he was already through high school and working in his trade.  I ended up heading towards IT because when I was working as a millwright I was the only one willing to take computer controlled systems on in a department full of older people who couldn't be bothered.

The idea that digital technology is opaque and unknowable is a continual professional frustration for me as a computer technology teacher.  Other educators, students and parents all buy in to this opacity even while they embrace information and communication technology in more aspects of their lives.  I understand the reluctance to make ourselves literate in this emerging technology, but if we're all going to use it I'd suggest we're all responsible for having at least a basic understanding of how it works or else we're going to all end up illiterate in a digitally powered world.

A bunch of smooth talking sociopaths have taken over the face of digital technologies, but I can assure you that Google, Facebook and the rest are not the limit of what digital technology can do for us.  Thinking that is dangerously reductive.  There was a time when the internet was newly birthed from academia and the people on it were exploring a new frontier rather than leveraging it in an Orwellian attempt to monetize our attention.  I'm a digitally literate person and I have no love for them, but I get the sense that Matt truly despises computing to the point of lumping any digital tech in with the sociopaths.  It's a hard distinction to make, though John Naughton does a good job of coaxing it out of author Shoshan Zuboff:

"While it is impossible to imagine surveillance capitalism without the digital, it is easy to imagine the digital without surveillance capitalism. The point cannot be emphasised enough: surveillance capitalism is not technology. Digital technologies can take many forms and have many effects, depending upon the social and economic logics that bring them to life. Surveillance capitalism relies on algorithms and sensors, machine intelligence and platforms, but it is not the same as any of those."


Another motorcycling angle to come at this from might be Neil Spalding's MotoGP Technology. This technical manual charts the evolution of the top prototyping class of MotoGP motorcycle racing over the past twenty years. These have been years of digital integration and management in terms of rule making and deciding how much of an influence computer assistance will have in the sport. Unlike Formula One, which many have suggested has gone too far down the technology path, MotoGP has evolved to focus on enhancing rider abilities rather than replacing them. Spalding mentions the estimate that F1 is an 80% car engineering 20% driver skill equation, where as MotoGP is the opposite. Marc Marquez winning championships on the third best bike would certainly suggest the humans operating MotoGP bikes matter more than the tech, and yet these are digital machines.

There is a point in the book where Spalding has to re-orientate the reader on how electronics work in MotoGP. Unlike what a consumer is used to, racing electronics have nothing to do with safety.  Their only intent is more speed even if it means more effort and skill is expected from the rider.  While everyone watching a race has only ever experienced electronic interventions (anti-lock brakes, traction control etc) as a safety blanket thrown over their incompetence, a racer only experiences them through the lens of performance.  Electronic intervention on a race bike make it more extreme and harder to ride.  
That alone should make the true breadth of electronics and digital technology in riding a bit more clear.  They are only self-driving us because someone wants them to for their own reasons, not because the tech is inherently focused in that direction.

Crawford often speaks of the mechanical work he's doing on various machines, but mechanical work doesn't end where a computer is involved.  There are some parts of vehicular evolution where automation is a much needed advance.  Crawford does make a point of mentioning this, but grudgingly.  Reading Classic Bike Magazine a few weeks ago I came across a great article about Dr Desmo, Fabio Taglioni, the Ducati engineer who spent his career continually looking for advancements for the brand.  His quote about computer controlled fuel injection is much like a MotoGP team's fixation on performance rather than protecting a rider from their own incompetence and is yet another reminder that electronic and digital technology does not have to replace human agency but can in fact enhance it.


Sorting out the Triumph's fuel injection system
by finding a modified fuel map and installing
it on the bike's FI computer was one of this 
year's most satisfying repairs.
I like getting a bank of carbs sorted out as much as the next person, and sometimes I make a point of working on bikes without electronics to distance myself from what I do at work all week (mechanical repairs offer a more immediate kind of satisfaction), but I've also had great technical satisfaction from the hybrid mechanical and electronics repairs I've had to make on the Tiger.  I realize that electronics and computer based repairs are often out of the comfort zone of the home mechanic, but that's based on the kind of anti-digital prejudice Crawford carries through his philosophy.  If we could all get passed that prejudice perhaps we could reclaim the digital tools we've surrendered to the attention merchants.

It's critically important we don't romanticize old technology for the same reason we shouldn't romanticize previous time periods.  If you think the 1960s were some kind of magical time in human history odds are you're a heteronormative, neurotypical white male.  From the point of view of the vast majority of the people on the planet the nineteen sixties were fucked, and so was much of the technology we were using back then.  That time of excess and privilege has led us to the brink of disaster fifty years later.  Longing to go back to it or recreate it is a kind of insanity.

This is distinct from respecting culture and engineering from a certain time period when it showed us a better way forward.   I greatly enjoy working on older machines in order to keep that history alive, but if you're putting on rose coloured glasses that make you blind to the possibilities of today's technology then you're just as manipulative as the sociopaths who are destroying society for their own gain.

Crawford talks about technology that is locked and closed, like Mercedes without dipsticks to check your own oil, or electronics that are sealed to prevent 'tampering'.  Corporations are able to do this because people have been convinced that digital technologies are something they can't comprehend, but this is bullshit.  The companies offering to do everything for you aren't technology companies, they are advertising companies.  Ignore them and ignore authors who dismiss digital technology as inherently nannying.  Modern technology can just as easily be used to enhance human ability and force us to be smarter, stronger and faster as it can be used to make us stupid, docile and compliant.  The issue is the intent of the people peddling it, not the tech itself.

If I can't convince you maybe Kenneth Clark's angle in 1969's award winning documentary 'Civilisation' will highlight things:


Clark's concern is that automation plays to the hands of authoritarian regimes.  He couldn't see the emergence of multi-national corporations that we're now under the yoke of back in 1969, but he isn't wrong about automation playing to fascists.  Crawford shares the same concerns, and they're well founded, but one of the best ways to take back control for more people is to make them literate in the technology being used to enthrall them.

All that to say don't be afraid of the digital aspects of motorcycle maintenance.  This tech was made by people so you can figure it out, and in doing so you will also teach yourself to author the technology the attention tyrants are using to snow you under.  From that point of view of self sufficiency and understanding of technology Matt Crawford should be on board.

Then vs. Now

I've been wondering why motorbikes don't seem to have moved on in the way that cars have.  To that end I'm trying to find comparisons between 1960s (pre-oil crisis) vehicles and current vehicles.  In trying to keep apples with apples and find stats for similar vehicles.  The problem is a 1960s Cooper Mini doesn't have anything like the crash worthiness of a new Mini Cooper, and that crash worthiness costs weight, though not as much as you might think.  The real cost in weight is our expectations around size.  The new mini is significantly larger mainly because minimalist, small cars don't sell.

Our improvements in engineering efficiency are often overshadowed by our need for bigger, more plush vehicles.  My thinking is that this shouldn't be such an issue on a motorbike, it's not like our bikes have gotten much bigger in the way that cars have turned into SUVs.

An example, the Mini Cooper.  The new car has nothing mechanical whatsoever to do with the old one.  Other than the name and marketing niche, these cars are very much creatures of their times.

So the new car is:
18% longer, 17% wider, 4% lower
46% heavier all with the same mileage!
                                       courtesy of Mini.

So what you've got is a much bigger car that offers all the modern amenities in addition to more space that gets about the same mileage, and it does it with an engine a third larger than the old one.  Put another way, the new Mini is about twice as efficient as the old one (it uses the same amount of fuel to move almost twice as much car).  On top of that Mini needs three less cc to get a horsepower out of an engine.  It isn't much, but it's an improvement, unlike the bike below.

Here is Honda's modern ode to the CB750:
The Honda CB1100A
Dimensions: 1490mm wheelbase
Weight:        248kgs  547lbs - wet
Mileage:       41mpg
Horsepower: 82.5 hp (13.8cc /hp)

At 1140cc, the new Honda is 390ccs larger, though follows the same engine layout as the old CB750.  They are within 3 cms of each other as far as wheelbase goes - bikes aren't significantly physically bigger in the way that four wheeled vehicles have put on weight in the past forty years, though cars seem to have done it while finding ways to get way more out of each litre of gas.   That new mini is a much bigger vehicle, almost twice the size of the original in terms of mass.  Bikes haven't grown anything like that, yet their mileage is pretty much the same.  

Keep in mind we were comparing a twelve hundred cc 1969 Mini with a 1.6l modern Mini, a 25% increase in displacement.   The new CB1100 has 33% more displacement on a heavier bike and gets the same mileage as the old carbureted one.  Why is the new bike so much heavier?  It's not like a car - it isn't larger than the old bike, it isn't carrying airbags and all sorts of other modern safety gear other than ABS.  To top it all off a carburetated 1969 CB750 used to use 10.82ccs to make a horsepower, the new one uses 13.8ccs to make a horsepower.  A lot of that could be tuning the engine for more torque, but here we are, 45 years later using more displacement to make less power?  What the hell is the point of fuel injection?

In 45 years of material development, the new Honda is 56lbs heavier.  The 1969 CB750 is within point one of a mile per gallon of the 2014 CB1100.  You might say it's not a fair comparison because they're not both 750cc bikes.  Honda's only current ~750cc bike is the NC750x, which is a parallel twin rather than a four cylinder.  Even with that disparity the NC750x tips the scales at 483lbs, still 2 pounds more than the 1960's 750 four cylinder.  And it's not like Honda isn't an engineering powerhouse.

If you say the motorbike vs. car argument isn't fair, how about motorbikes to bicycles?  A Tour de France bike in the 1960s weighed about 22lbs.   Modern bikes are limited to 15lbs, though in 2004 Armstrong had a 14.5 lb bike and without the limit a 10lb bike is more than possible.  If bicycles have dropped 30% of their mass in the last 45 years, why not motorbikes?

If we look at this from an automotive/bicycle equivalent efficiency angle, the new Honda CB750 should have a 20% more efficient engine and weigh 30% less.  The 2014 CB750 happy memories bike should get about 80mpg, weigh 344lbs and produce about 82hp.  This bike would have a power to weight ratio of about 4.2lbs per horsepower, approaching what some of the fastest sports bikes in the world have.  The sensible choice then would be to make the bike a 650cc CB throwback, which still produces a  better power to weight ratio than the CB1100 and weigh even less with the smaller engine.

I asked before and I'll ask again, why haven't bikes advanced at the same rate as cars (or bicycles)? Why isn't the new ode to the CB750 a CB650cc bike that produces more power, uses less gas and rides far better than its prehistoric inspiration?  Motorbikes are stripped down, simple machines, in many ways still very similar to the machines made decades ago.  With that in mind, why don't we see the radical evolution in technology evidenced in the Mini and in racing bicycles in the past 45 years in the Honda CB750/CB1100?  If we aren't larding up bikes into SUVs (though some people are), the efficient burning of gasoline should have produced astonishingly high mileage numbers by now.  Where is the direct injection? Where are the intelligent drivetrains and engine management systems that have produced cars that weigh twice as much and still burn the same amount of fuel?  Where is my frictionless magnetic drivetrain with integrated brakes?  Where is my kers?


With an integrated kers system, I could be riding a 400cc bike that when the kers kicks in feels like a 1000cc bike, then recharges while I ride.  I could pull onto the highway or overtake on a super light bike that can feel like a one litre rocket when I need it and sip fuel like a 400cc machine when I don't.


Zero Motorcycles: all electric, but I don't know that we
have to go to that extreme yet, we're not exploring
internal combustion that well.
Because motorbikes are small and inherently efficient compared to cars, manufacturers haven't pushed engineering limits in the way that they have with other vehicles.  I'm looking for the future of motorbiking, and it doesn't feel like manufacturers are testing limits in a way that makes my choices feel any different than they were a decade ago, let alone four.

Future Bike

WIRED recently did some articles based on the Tokyo International Motor Show.  I spent a couple of years in Japan paying off all the debts I accumulated living in North America.  I've got a soft spot for Japan and the tech they produce.

Kawasaki's neon green ode to anime bikes scratches that anime itch, though it is fairly ridiculous.


Of more interest from an engineering point of view is Yamaha's ultralight bike.  Since watching McGregor and Boorman trying to right seven hundred pound BMWs in the Long Way Round, I've wondered why bikes aren't lighter than they are.  Why aren't we getting more horsepower out of smaller engines and saving weight that way?  Why aren't we using our modern engineering prowess to build bikes with smarter materials?

Case in point, as a high school student I thought the Honda Interceptor was awesome. It weighed 443lbs ready to go.  The current 500CBR is a modern equivalent, wet weight? 428lbs.  In thirty odd years of materials research and development a company as forward thinking as Honda has managed to shave 15 pounds off a bike's gross weight?

How about Triumph's last year of the original Bonneville?  A 750cc bike, 441lbs.  The new one?  496lbs.  It's a bigger engine, but it would need it to lug that fat ass around.  Even Triumph's brilliant and athletic naked Street Triple still tips the scales at over four hundred pounds.

Motorcycles are, by their nature, minimalist forms of transportation, but instead of finding ways to make them even lighter and more efficient we're SUVing them just like we did with four wheelers.  Bikes like KTM's new 390 Duke give me some hope though.  At 300lbs I bet 390cc has never felt so powerful.

I can't help but feel that alternate building methods and advanced materials haven't been explored by conservative
motorcycle manufacturers.  Yamaha asks a good question when it asks, where are the two hundred pound motorbikes?

McLaren could put together the three seater 200mph+ V8 F1 super car twenty years ago with a curb weight of only 1062kgs (about 2340lbs).  We've got massive cruisers tipping the scales at 900lbs, meanwhile Mercedes-Benz is putting together Smartcars that weigh only 1600lbs.  Even a back to basic bike like the KLR650 with only a single cylinder and basic bodywork still weighs in at 432lbs.


A bike frame in one hand? It's possible,
but bike manufacturers aren't
considering it?
I'm still not a fan of electrical bikes as long as we're stuck with medieval chemical batteries.  With lousy storage and even worse disposal characteristics, rushing into electric bikes right now isn't the way to go, though one day I hope to see an unlimited charge bio-tech battery that recharges off the buried kinetic/flywheel battery under my house.

Our issue with electricity isn't the making of it, it is the storage and transmission of it.  One day I hope to be able to unplug my bike from my locally generated and stored electrical system and get a thousand kilometres out of it before I have to plug it in again.

There are levels of efficiency we still need to move through in order to get to that place and the conservatism and marketing focus I'm seeing in bike manufacturer aren't moving us in that direction.  A little less focus on building to marketing niches and a bit more focus on advancing engineering would help us toward a necessary evolution in motorcycling.

While Formula One develops energy recovery systems that also act as full on torque turbo-chargers, perhaps it isn't too much to ask bike manufacturers to go after other areas of efficiency such as weight improvements in chassis and drive-trains.  I'd very much like a 400cc bike that weighs only 200lbs.  From an efficiency point of view it would be unbeatable as a means of transport and something that would get many more people interested in riding on two wheels.
