That's not why they are coming in on trailers. Tesla brings a loaner car to your home or business and takes your car back to their facility to work on it. They could be coming in for service or a tire repair. My buddy is a service writer for Tesla and he doesn't even have to leave his home. Everything is done over the phone or through email. For smaller services they just dispatch a mechanic directly to your location and the car is serviced there.
News flash, people buy $100k cars every day. Maybe not you or I but they ARE selling. These are not tree hugging hippies who want to go green. They are people that have a butt load of cash and want to drive something fast and don't want to pull into a parking lot and see five cars just like theirs. It probably eases their conscious a little that they are driving an electric car, but the reason they're buying them likely has more to do with their ego.
Actually, what I was referring to with my future comment was the fact that people are always posting about "where are the flying cars that we were supposed to have in the 21st century?!?" I was merely pointing out that the car basically drives itself. Not our cup of tea I know, but still pretty cool technology.
