I wonder if they will eventually license the self-driving software in an Android-like model?

Doubtful. Most of these companies want to own the tech. I'm actually concerned they won't be able to sell it if they tried - Chrysler is actively developing a self-driving system that they hope to deploy in 2 years.

Everything Google does feeds back, somehow, to data mining. How does self-driving cars fit in to Google's plans? ETA: Downvoted for asking a serious question? WTH?

What do you think a bunch of people in self driving cars with smartphones or personal wifi hotspots are going to do? Surf the internet, and therefore use more of Google's products. It's similar to Chrome or Android in that it enables more people to use Google's core services which they make money off of.

Well, the car itself becomes a device, right?

- Active internal displays that push ads based on detailed mapping information. - Delivering you to a particular location after you look it up on Google. What's the Price per Delivery (PPD) on AdWords?

The technology is impressive, but humans drive okay without LIDAR, radar, or GPS. Maybe some day self-driving cars can drive using only two small visible-light sensors located above and behind the steering wheel. It might just be an AI challenge to operate that way, and commercial systems will always employ advanced sensors for better safety. But I don't think true parity has been reached until they can drive like we…

But people aren't very good at driving, it would be silly to try and handicap computers with the features we evolved. Every new car made already has lots of advanced technology to make up for our two eyes.

Once legislation is updated to allow self-driving cars in most parts of the world, I wonder how profitable self-driving cars could be for Google. About 77 million cars were produced in 2010. With the appropriate licensing, a percentage of that could make a very nice profit. I should buy some Google stock :)

I wonder how long will it take till the price of something like this gets to reasonable levels. The lidar and other sensors probably won't get cheap anytime soon. Imagine the costs of Google having to drive through all the places first, mapping them. Then the massive insurance until its proven that self-driving cars are safer (and then it will probably get expensive again after a first accident) Perhaps it would make…

Not to speak like a party-pooper, but could someone potentially mess with this LIDAR system by aiming a very bright IR beam at the device, if not a matching laser itself?

Bringing down the cost of the LIDAR will be one major task, the other will be making this untouchable in the environment, IMO.

> With its full 360° horizontal field of view by 26.8° vertical field of view, 5-15 Hz user-selectable frame rate and over 1.3 million points per second output rate, the HDL-64E provides all the distancing sensing data you'll ever need.

That's pretty interesting. I would have thought that they needed data at a faster rate than 15fps.

You could probably screw up the samples that would be taken from wherever your beam hits on the mirrors. But you could also shine a laser in someones eyes while they're driving and seriously impair them as well.

Don't forget that humans also have a pretty good accelerometer and sound processing built-in, which helps. But it's true, we are much better at object detection and recognition.

It is normal for pedestrians to look for eye contact in order to know if a driver will yield the right of way or simply will accelerate and pass (in light less crosswalks). In dense pedestrian cities (I am from Spain) it is very usual to have some guessing and false start stop between the pedestrian and the driver, nobody seems to know who is going to yield finally. I wonder if this is been thought and how you'll sig…

I too thought of a forward braking light. When self-driving cars become common enough, people would learn to interpret it.

Agreed, I don't think we should strive for parity. I'd much rather see driverless cars that are better than humans at driving, even if they need more tools to do it. The more poor drivers we can replace with driverless cars, the better.
