My biggest question relates to stuff on the road. That includes oil, or ice/snow.
I am sure the car understands the current road conditions based on the traction of the road just underneath the car, but what about oil, or black ice 50 feet in front of it.
Sure the car can drive in a straight line and measure distances between itself and the car in front of it, but what about the northern neighbors who deal with roads that are temporarily slick or where there has been something spilled on the road?
I am sure that people will still be held 100% accountable for the decisions made by their cars. Which means you will still have to be paying attention in any situation where the car wouldn't notice a problem but a human would.
This might be great in southwestern states, but Boston/New York? I don't think this will fly.
An autocar with a decent sensor package will be much better at detecting changes in road condition then a human would be. Not only does it have all the sensor data from it's camera's, radar, thermometer, hygrometer, accelerometer, and traction, and probably a dozen other instruments I haven't even thought of, but it has all that data from the cars in front of it as well.
And when things do go wrong, and it does not detect the road anomaly in time it will be much, much better at performing the proper action to correct for the sudden change, while most humans do exactly the wrong thing.
