I'm in the "my car is mine alone" category. If you wonder why just peek in random cars the next time you are at the supermarket; it isn't always pretty.
And let's not forget the treatment of rental vehicles in general; I think it is second only to Top Gear test vehicles in terms of abuse.
Plus I'm fairly certain your insurance company would make you pay for this privilege, if just for liability reasons. And this is even *if* Tesla offers an insurance package to owners who rent out ala Uber, as I'm sure that package wouldn't replace your insurance just supplement it. Given that, how much money will be left over from that rental when it is said and done?
It is one thing when full autonomy means that you are just renting to passengers, not drivers. At least then it is just a matter of protecting your interior as much as you see fit (and hoping people don't smoke).
