Thoughtful post, and quite interesting. I think you might be dramatically missing some points, however. Consider Digital Nomads. Estimates I have seen indicate that there will be as many as 1 Billion such independent travelers by 2035.

With autonomous vehicle technology, consider what benefits would inure to this demographic from having RVs. Long haul travels, satellite internet, and RV parks.

I don't see car ownership being extraordinarily reduced, even for non-nomadic people, as long as kids need a place to get laid, smokers can't use public transportation, and various cargoes cannot be transported via commercial lines.

Neither do I see cops being reduced, given the political landscape that seems to be emerging, not only in the USA and EU, but globally. Police states are on the rise, and new excuses to police autonomous transport are going to arise.

I expect there will be pushback, but cops are gonna surveill us, and it is a given that outfits like the NSA will be able to do so using our vehicles as the surveillance device - unless there is some move to preclude it, which I have seen no sign of from any vehicle manufacturers.

Onstar, GM's innovative surveillance product, has long been used by police to both surveill and compromise vehicles of interest. Just as your cell phone can now be used to track you, listen to you, and see what ever the camera is behind, even when the phone is ostensibly off, so will vehicles equipped with wifi, cameras, and mics.

There will be dramatic changes, but mostly 'meet the new boss, same as the old boss.' If we really want to reduce the impact of surveillance and police state forces to more intensively control us, we're going to have to institute radical changes in how this technology is developed.

Given our divided and conquered state at present, I don't see it happening.
