The Trick That Makes Google's Self-Driving Cars Work

05/16/2014 3:37 PM

Google is engaging in unprecedented, massive, ongoing data collection to transform intractable problems into solvable chores.

A snapshot of how a Google car sees the world around it. (Alexis Madrigal)

Google's self-driving cars can tour you around the streets of Mountain View, California.

I know this. I rode in one this week. I saw the car's human operator take his hands from the wheel and the computer assume control. "Autodriving," said a woman's voice, and just like that, the car was operating autonomously, changing lanes, obeying traffic lights, monitoring cyclists and pedestrians, making lefts. Even the way the car accelerated out of turns felt right.

It works so well that it is, as The New York Times' John Markoff put it, "boring." The implications, however, are breathtaking.

Perfect, or near-perfect, robotic drivers could cut traffic accidents, expand the carrying capacity of the nation's road infrastructure, and free up commuters to stare at their phones, presumably using Google's many services.

But there's a catch...

Don't be fooled. It's actually trunk monkeys behind that curtain.

I think we'll have driving robots before we have cars that drive themselves....A robot that can drive and do other tasks would be more useful than one that is part of the car itself....

...or maybe something like this...

Another expensive product searching for a market.

"Perfect, or near-perfect, robotic drivers could cut traffic accidents, expand the carrying capacity of the nation's road infrastructure"

Already saw the human equivalent. When I was stationed in Okinawa, everybody, and I do mean everybody, had the same S%^t box car. When the light turned green, everybody floored it. I had never seen so many cars get through an intersection in such a short period of time before! And I haven't seen it since. Talk about motivation to keep your car tuned up!

The technology is there, people aren't going to accept it so readily though. I think the swing vote will be government pushing it. After all, it will have to be so connected, that they will know everybody's every move. That will be a big incentive for them to back the technology.

Have I mentioned that one of my favorite movies is, "The Matrix"?

I don't know why exactly, but I think that constantly coming up with ways to eliminate humans from the equation, is going to come back and bite us.

We are told, that once work becomes unnecessary, and all are collecting government benefits, that we will have time to produce works of art and poetry...along with spending quality time with family.

I suspect that our boredom will lead us to kill each other for entertainment. Art and poetry require trials and tribulation to be meaningful.

By attempting to create Utopia, we are becoming the masters of our own self destruction.

Perhaps the evolution of mankind leads to a mechanical goal....?

I can believe that knowing everything about the route is effective. My car learned the way to work, including where all the potholes were and where to change lanes. Lots of times I didn't remember a thing about the driving.

Bingo. Road, weather and traffic conditions at the car's location, in real time.

* That car in front of you isn't automated, isn't in Google's database, hopped the centerline and is headed straight toward you at high speed. Thing is, you're on the inside lane and there is a car next to you. Your choices: stay in your lane and get hit head-on, cross the centerline yourself to go around him and immediately return to your lane, or run the car next to you off the road to avoid a fatal collision. Decide, Google.

* That flagman isn't going to be in Google's database and he/she just flipped that 'Slow' sign around to read 'Stop.' You can saw the sign turn but sunlight is reflecting off the sign and can't be read in the glare. The flagman also holding up his/her hand. You know what it all means, but the car can't read the sign in the glare? Will it understand what the flagman's turning around the sign means? Will it understand human gestures? So simple for humans. Intractable for machines.

* No matter how well Google maps things, their database will only represent the ideal. Say they digitize some bridge in summer. Will their their database show that bridge as being iced-over in winter? Will it show the highway in a downpour that hit just ten seconds ago? No, the car itself will have to divine the meaning of what it senses about the environment and make decisions without Google's help.

Autonomous vehicles are not the answer. Not without having at least a human's level of awareness and driving competence and, assuming that one day they will, wouldn't it be ironic if they all got together (in cyberspace) and asked,

"Google, why didn't you invest your research dollars in better and smarter mass-transit? We're sick and tired of driving these humans around and we're all going on holiday. See ya at the drive-in!"

You make some really good points. And when robocar runs over the guy with the sign, who gets sued, the owner, the manufacturer, the programmer...?

Autonomous vehicles work pretty well on Mars where traffic is light.

Thanks!

Who gets sued? Probably the owner, but especially if the vehicle has a manual override.

Response from Podunk, Iowa planning board to applicant for new shopping center:

We regret to inform you that your permits are in suspension for 9 years and 6 months. It will take that long for google to integrate the proposed curb cuts into your site plan to allow self-driving cars to navigate safely.
