A Sober Second Look At Self-Driving Cars

a sober second look at self driving cars

While TTAC‘s Mike Smitka published an essay urging readers to reign in their expectations regarding autonomous cars, a new report by MIT’s Technology Review pours even more cold water on the utopian fantasies of those waiting for the day when humans are no longer in control of the automobile.

While the full text is available at MIT, the American Enterprise Institute summarized the obstacles faced by autonomous cars in a series of handy bullet points

The self-driving car can’t drive itself in 99% of the country.
It knows almost nothing about parking, and can’t be taken out in snow or heavy rain.
If a new stoplight appeared overnight, the car wouldn’t know to obey it.
Google’s cars can detect and respond to stop signs that aren’t on its map, but at an unmapped intersection stop sign the car wouldn’t know what to do after it had stopped, and would probably remain stationary until a human driver intervened.
The car hasn’t yet tackled big, open parking lots or multilevel garages.
The car’s video cameras detect the color of a traffic light, and they’re still working to prevent them from being blinded when the sun is directly behind a light.
Pedestrians are detected just as moving, column-shaped blurs of pixels—meaning that the car wouldn’t be able to spot a police officer at the side of the road frantically waving for traffic to stop.
The car’s sensors can’t tell if a road obstacle is a rock or a crumpled piece of paper, so the car will try to drive around either. The car also can’t detect potholes or spot an uncovered manhole if it isn’t coned off.

Given all of the breathless hype regarding the technology, and Google’s introduction of their own prototype, sans pedals and steering wheel, it helps to have a contrarian viewpoint to dampen some of the exuberant enthusiasm professed by many who are better versed in the tech side of things, without understanding the unique subtleties of the auto world.

These are hardly show-stoppers. They are merely a few more items to include in the final solution. The future is already here, it's just not evenly distributed. It's silly to think autonomous cars will suddenly appear everywhere at once. They will appear on the Google campus & other controlled locations, then expand. We already have autonomous cars--self parking, radar cruise, lane-keep, auto braking, etc. these features will simply continue to get more inclusive, and human involvement will continue to decrease. As cars get smarter, we will build smarter infrastructure: V-to-V, V-to-I. Car can't 'see' a new stop sign? Well that new stop sign will be smart so that the car will automatically work with it--same with lights and parking lots/garages. It will be a transition, but it will happen.

Pretty much all of that is fixable with software and infrastructure improvements. Bitching that it can't park? I mean come on. We aren't even looking at the model t here, we're looking at a prototype of the prototype. It's early days yet, but I'm quite sure that a computer can and will be a much safer driver than the average driver. The computer never gets distracted, drunk, sleepy, or old. Automated cars would save tens of thousands of lives every year in the US. This is like saying personal computers will never be big because the Atari 7200 just isn't that much better than a typewriter.

  "The computer never gets distracted, drunk, sleepy, or old." Good point. I guess you could say that right now self-driving cars are stupidly young...they're the equivalent of a 16-year-old who just got his license. Yeah, legally he can drive, but probably not too well, and almost certainly not in a crisis situation.

  Actually, there are other problems like not being able drive in snow or heavy rain. As far as being distracted and old, that can happen to computers. The distracted situation could happen if there's a lot going on and the computer can't process everything that's happening as quickly as it needs to and the aging think does happen to chips and sensors which can cause failures. The problems go much further than what additional software alone can fix. As we slap on software to solve problems, hardware performance demands increase exponentially. The good news is that this month IBM announced new hardware that should get the job done. There's going to be a huge learning curve in developing software for a somewhat new architecture (neuro-synaptic), but at least we can start making some real progress. http://www.almaden.ibm.com/laborday/cognitive-computing/neurosynaptic-chips.shtml

  @Roader they’re the equivalent of a 16-year-old who just got his license Maybe closer to this: https://www.youtube.com/watch?v=BWAK0J8Uhzk Actually, the Google cars are probably closer to maybe a 6 or 8 year old. Remember, there are plenty of situations where there has been hand-offs to humans.

  @mcs If the computer can't cope, a person would be utterly lost. Snow and heavy rain also solvable. If people can do it, a computer can figure it out. As far as aging goes, that can be resolved by a conservative maintenance and replacement regime. 50 years from now I'm very confident that people will look back at this era and shudder about how we let people drive three ton murder machines with only the most minimal training or competence.

Spamvw Did clears to my '02 Jetta front markers in '02. Had to change the lamps to Amber. Looked a lot better on the grey wagon.I'm guessing smoked is illegal as it won't reflect anymore. But don't say anything about my E-codes, and I won't say anything about your smoked markers.
Theflyersfan OK, I'm going to stretch the words "positive change" to the breaking point here, but there might be some positive change going on with the beaver grille here. This picture was at Car and Driver. You'll notice that the grille now dives into a larger lower air intake instead of really standing out in a sea of plastic. In darker colors like this blue, it somewhat conceals the absolute obscene amount of real estate this unneeded monstrosity of a failed styling attempt takes up. The Euro front plate might be hiding some sins as well. You be the judge.
Theflyersfan I know given the body style they'll sell dozens, but for those of us who grew up wanting a nice Prelude Si with 4WS but our student budgets said no way, it'd be interesting to see if Honda can persuade GenX-ers to open their wallets for one. Civic Type-R powertrain in a coupe body style? Mild hybrid if they have to? The holy grail will still be if Honda gives the ultimate middle finger towards all things EV and hybrid, hides a few engineers in the basement away from spy cameras and leaks, comes up with a limited run of 9,000 rpm engines and gives us the last gasp of the S2000 once again. A send off to remind us of when once they screamed before everything sounds like a whirring appliance.
