How will autonomous cars effect real estate trends?

[Rick C.]

Over the years, there has been a growing demand for walkable communities. At a quick glance, this has been shown in the form of people moving into more densely populated areas, such as cities and downtown areas of suburbs.

In less than a decade though, autonomous cars will be available to consumers. I am curious how BPers believe this will effect real estate trends. Will it promote suburban sprawl, since having a long commute will not be as stressful? Will it further enhance density, because it will be easier/cheaper than ever to take a cab or use a car share service instead of owning a car?

Overall, what do you think will be the effect of autonomous cars on real estate trends?
