> I really want to like electric cars (and trucks, sure) but I don't like that you don't really "own" them. I don't know of any that you can buy that don't require signing up with the manufacturer and having to install an app on your phone, or have the car permanently connected to the cloud via mobile network, just to drive and charge the damn thing.

That's not an electric car problem. All cars are going to end up that way.
