Certain predefined and tested functions like stopping at red lights, stopping and moving around random double parked cars, slowing down for random raccoons, stopping for random people, making safe left and right turns while in traffic, navigating down roads with little or no markings, pulling to the side of a road, safely merging back onto the road, and just generally cruising around a busy city like San Francisco. Seems like a pretty compelling "demo". Remove the raccoon and that sounds like a typical day for me behind the wheel.
At the end of the day, competition is a good thing. I am rooting for all of them.
