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…

Somebody correct me if I'm wrong, but Google cars still can't drive in the rain or in the snow. Not even on a wet street. They have driven all those thousand miles in Mountain View, Calif. in good weather. Generally lidar's don't work well with rain or reflective surfaces.

My understanding is that it uses vision processing algorithms on a camera nowadays, and works just fine in rain. Snow is an issue because the car can't see the lane markings through the snow -- a human drives through snow by remembering where they were or making a guess.

Wow. You are giving waaaayyy to much credit to the responsiveness of humans. Roughly 1 in 4 drivers have a statistically significant amount of alcohol in their blood system. Lets also not forget distractions like cell phones, finding/selecting music, passengers, OTC and prescription drugs, et al. From my perspective, I'm the only good driver on the road and everyone else needs to go back to driving school or have the…

1 in 4 seems high, especially if you mean to the level of impairment. I'd be interested to see the source of that statistic.

> 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 d…

I personally think society is going to have a much harder time accepting death by software bug, than human error.

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

I absolutely agree, and I now feel like offering to cyclists a t-shirt that reads in bold “We WANT Google self-driving cars.” and maybe, in tiny ‘Because, if you can read this, your driving sucks and you don’t respect security distance.’

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)

I want to see the self-driving car on place de l'étoile on a busy day. Or in more or less any south-east asian metropolis.

somehow the current scuffle between uber and regular cabs seems to miss the joke. we're going to need a plan for the eventual unemployment of a lot of cab drivers, regardless of how the cab is hailed.

Even New York City seems to only have tens of thousands of cab drivers ('seems' because I just looked at wikipedia for a minute), I don't think they are that big a percentage of the population.

My Volvo already has a system that is better at that than me: https://www.youtube.com/watch?v=5nfT9dfPi7g

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...

There was a report some time ago about making the cars be somewhat aggressive. If I recall, they had a lot of trouble with left turns until they programmed in some lurching forward behavior.

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

> very little regard to any regulations.

That's an important point, I never expected lanes count and lane direction to be interpreted as suggestions until I saw people going through a roundabout on both sides at the same time.

Given that the NSA will likely have a backdoor into any automated driving system, is this really a technology you'd like to see become all pervasive? "We don't like this guy's ideology - ok, let's arrange for him to have an 'accident'".

They control killer robots in the sky with missiles... It doesn't really get worse than that...
