I love the idea of smaller, more efficient vehicles, but I think we hold too much hope in the fact that they could be "self driving". Why would a smaller self-driving car be more likely to gain in popularity over what most people choose to drive today? Why is it more likely to be electric? Those are two independent characteristics that haven't taken off on their own; I don't see how the self-driving aspect is going to change many of the existing problems we have with car-based transportation.
