There's a great presentation about Google's self-driving car here (check the second half for video of the real-time telemetry that it gathers):

One of the things that I found really interesting is how the car inches forward at a stop sign in order to show the "driver's" intent to other drivers. Lots of actions that seem to be second-nature for human drivers have to be carefully emulated here.

Thanks you for the link. It looks like the picture here is almost the same as what is shown in that video (from 1.5 years ago).

It is exactly the same. The picture on Twitter was the frame shown on 9:07 in the video. Given that the image is from a 1.5 year old promo video, which probably has been circulating all over, that puts the rest of the information in a new perspective as well.

Here’s a comparison I just put together: http://imgur.com/IfxYZL2
