Bikes are a superior solution in some places, but they're just not compatible with the existing infrastructure and culture in others. You'd have to redesign neighborhoods, add transit for long distances, convince people to live more densely, raise a generation of children who are fit enough to ride and aren't scared of heat and cold, etc. I think that's worth doing and the Netherlands and Scandinavian countries have set a pretty good example but that took them generations. Whereas self-driving electric cars can simply slot into our existing auto-centric cities and towns without requiring Americans to change their behavior, get exercise, or experience any sort of discomfort. Sure, they solve only a proper subset of the problems caused by cars (e.g. tailpipe emissions, parking) so they're more evolutionary then revolutionary, but I suppose they're better than nothing.
