I'm okay with car-as-a-service model as long as I don't have to buy the actual car, and pay only for the right to use a car, and any available car in the Tesla system, and in which Tesla deals with all breakdowns, charging, and maintainence, quite possibly by having the cars automatically take themselves offline from the rideshare system and self-drive themselves to a repair center when they are close to needing maintainence, while sending me an alternate car in its place. This would actually be a really nice transportation system to use IMO, and it's the maintainence-free aspect of it that I would value in a car-as-a-service model.

I'm strongly against a hybrid model in which I purchase and own the car, am responsible for maintaining it, but I can't tweak it on my own to do whatever the hardware is safely capable of. I actually wish there are laws protecting the right of the owner of any hardware to tweak anything they own. I mean, it's my property after I bought it.
