One key benefit that self-driving brings is the eliminating the need for curb-side parking. Your car can drop you off and go park itself in a hole somewhere. That opens up space for many more bike lanes where light motorized vehicles like Segways can also operate.

A lot of positive development can occur with the right regulations. That's what governments should focus on. As we've seen though with the fiasco that's the taxi market in US cities, public officials aren't too keen on doing their job proper.
