I think that race through a city would be much more difficult than a desert. Rocks and bushes don't move, now imagine trying to merge with traffic. The video processing would have to be absolutely amazing to distinguish stop signs, traffic signals, turn signals, brakelights, from the tons of store signs all along the street. Also, there is a lot more potential danger and cost from a collision. It will be interesting to see what people come up with.
