This is better solved by leveraging more traditional forms of transportation. Making biking, walking, and various forms of transit easier, safer, and more effective. Cars, whether self-driving or not, are in direct opposition to this.

I'm sure they could be useful to folks that have the specific use-case for it, but the vast vast majority of trips in a person's day-to-day are better solved by robust multi-modal options and public transit. The benefit there is that less drivers means that traffic is actually better for everyone.
