Interestingly enough, a car which simply refuses to drive in hurricanes, hailstorms, white-out snow, and so forth would be rather more than 20% superior to the average driver. So that's easily dealt with - if insufficient sensory data is available, either hand control over to the driver or, if possible, pull to the side of the road. The average driver likely does really horrible in large crashes and pileups, so merel…

car which simply refuses to drive in hurricanes, hailstorms, white-out snow... While admitted these conditions can sometime be anticipated, I think the point is that sometimes these conditions cannot be anticipated. You experience a sudden white-out a minute after a snow storm starts. What do you do? Breaking immediately is not the answer! (thus, the cars will need to drive...)

White-out conditions are much easier to see through with radar than with visible light. I think the computer will easily top us on that one.

If anyone can make this work out to be used by the public, Google can. They seem to be fairly good at pissing off established business. (Though they're still learning as Android shows.) Demos are great, just reinforces that Google is really an AI Company.

Where my pessimism lies for this reaching the public even if it's technically sound is that there are a lot of established multi-billion dollar businesses to contend with. Insurance is a big one, traffic tickets are another.

How Ironic. My very first job out of college, in 1995, was working for an avionics firm that was developing a system called "Tundra Tracker" - that would allow vehicles to navigate in whiteout conditions in the far north. I had the amazingly easy portion of taking the DGPS coordinates of maps/previous tracker runs and turning them into navigation maps. Challenges with the (dynamic) appearance of people, other vehicles, animals (Moose will ruin your day) crevasses, and other elements on the path were left to others to solve. :-)

I would really like this on top gear and compare it to the other drivers on their closed course. I wonder how well it would do in their celebrity challenge that they do every episode?

If tuned to a single track it should be completely unbeatable, right?

If that were the case, then Shelly, the car racing up Pikes Peak would have been able to beat the human time of 11:21, instead of it's recorded time of 27 minutes.

Unless all cars are driven by machine, the driverless car won't make a huge difference in our lives. You can already experience the magic of not having to drive by paying someone else to do it for you. The real gains of automation occur when a machine doing the job can do it faster than a human. Computers calculate and communicate faster than people, and factories/robots build stuff faster. A machine driving a car ha…

Rush hour in major cities would be an entirely different experience with automated cars. In my observation, the vast majority of congestion is caused by drivers either overcompensating for changes in conditions (ie slowing down even more than the car in front of you slowed down) or otherwise reacting slowly. I believe highways could handle considerably more traffic if all the traffic were automated. I think it's poss…

Left lane for automated cars, right lane for manual prudes.

In mine and a lot of others' observation the main cause of traffic is people's inability to merge. People suck at it. And that in turn creates traffic waves... http://trafficwaves.org/

There's still a problem to solve though: who's going to accept payments, process credit cards, verify signatures etc.

Just like there needs to be people who do that at Amazon, Zappos, etc... Honestly, a taxi with only a Google maps interface and a credit card swiper would be interesting.

No more tipping!

Sounds like the Watson for cars. It'll happen.
