I don't know how they can possibly be programmed to drive in a city (think New York, Boston, Washington DC, Miami, etc.). You HAVE to drive like an ass or you will never get anywhere. You need to take chances, be aggressive and at times play chicken with other drivers when pulling out in front of someone. Otherwise, walking would get you to your destination faster.
Maybe driving in the rural Midwest or something would work to a point but anywhere there is a lot of traffic I don't see it happening.
