This is hardly city driving. Try driving in a European city. (I love this project and can't wait to buy or rent a self-driving car)

Harder yet, Southeast Asia. Hundreds of pedestrians, tons of vehicle variety (some entirely makeshift), uncontrolled intersections, very little regard to any regulations.

It won't be able to drive around New York if it follows the rules so strictly. It will never be able to turn. They'll have to add a setting for aggression...

That's funny, but probably a very real challenge. As a (human) driver, it happens that we come across ambiguous, contradictory or just plain impossible constraints and we overcome them by deliberately breaking the rules. I wonder how they would cope with that?

As a city cyclist, the Google solution looks way safer than the current status quo...

Even before we get self-driving cars, autonomous braking should be mandated so that cars and trucks are literally incapable of coming too close to a cyclist.

If I remember correctly, they already have one.

The next step is highways!

as a theoretical problem highway should be much easier because few types of "street agents" can access them (i.e. no bicycles, no pedestrians, no traffic lights)

As far as I know, they already have a pretty good handle on limited access roads.

People use 'highway' to describe all manner of roads, I wonder if the gp is thinking about major 2 lane roads that have higher speeds but still lots of intersections to deal with.

This is amazing, but if anything it's made me more wary of some of the challenges the project faces. - What if the cyclist fell off his bike in front of the car? How quickly can the computer process the real-time imagery and react compared to a human with their peripheral vision. - What if the cyclist swung from the pavement on to the road. A human driver will probably have spotted the hazard (we all train for that k…

> The sad truth of this is that whilst it's an interesting technical challenge, I really can't forsee a situation where a computer could react to all the different things that could happen when driving a car as well as a human.

I agree, at least for some time. But it's not about a computer reacting to as much as a human. The question is, can a computer can do a better job overall (e.g. drnk driving or texting while driving accidents are eliminated)? So dont look for a perfect driving record, as humans have loads of accidents today. As long as the computer has less frequent or severe accidents it is a welcome improvement to our roads even if it does have infrequent limitations.

I love how the car understands the cyclist's hand signals. The self-driving car is going to have a gigantic impact on the world, I can't wait to see it commercialised.

As a cyclist, I was shocked to see the cyclist change his mind like that —unless he was a tester too, that’s how you get bumped– but I really hope Google Cars learn that most cyclists actually don’t signal their turn that well.

Cars don’t bother either, and the last frame show how most non-car drivers get killed: don’t notice what passing just being, shift in gear, swerve and… bang. Seeing how Google taught its car to behave literally had me shout in joy an dance at my desk.

There are over 30,0000 deaths in the US alone every year, which is actually near historical lows. I believe there are several million accidents and hundreds of thousands of injuries. Now the computer might not be perfect but if it's 10x better, wouldn't that be acceptable?

Getting to that point is the challenge. I'm just throwing out questions and raising the point that there are some very very hard challenges to solve, where humans are probably much better.

I saw an interesting comment on the blog post. Is anyone keeping tab on the project knows if Google in working on some sort of communication between vehicles on road. That will make the self driving cars much more accurate. Lot of 'sudden' circumstances will be predictable by the car.

This would also be better for optimal traffic routing. I remember reading about it previously somewhere, but it gets bad PR for privacy reasons so I think it's brought up less often.
