1. I've noticed that adaptive cruise control doesn't account for vehicles entering my lane in front me, even with their turn signal on. As a human driver, I see them entering and know to slow down (at least take my foot off the gas), but the system only performs a hard brake AFTER the car has actually moved into my lane. Disclaimer: I don't know if autopilot systems suffer from the same limitation.
2. I was once waiting to make a protected left turn at a busy intersection. There were two protected left turn lanes, and I was in the farther left lane. Light turns green, I take my foot off the brake, and prepare to accelerate. The car on my right, in the other left turn lane, is also barely starting to move forward, when it suddenly rocks to a halt, indicating they applied the brake, hard. Without thinking, I also brake hard. Out of nowhere, a car appears speeding right through where I would have been if I hadn't stopped. Apparently, this car was entering the intersection on the cross street, going right to left. He wanted to beat the red light (he didn't), and also make his left turn, right down my street, in the opposite direction I was headed. I guess he didn't realize there were two left turn lanes. I never saw him. If I hadn't gone with the herd instinct and hit the brakes, I'm sure there would have been a serious impact. I wonder if autopilot would have caught that one, but it probably depends on camera placement.
A single self driving car probably wouldn't (might do the same thing you did at best).
It'll take actual inter-vehicle communication to extend the sensor-net. Much like humans presently do via proxying though the other car's deviations from anticipated behavior. (EG if the freeway traffic keeps going at proper speed around corners)
