You are aware that real self driving(L5) is not possible without some AI breakthroughs, right? All the promises you see from Elon are just pure BS. Your tesla has issues seeing a big truck straight in front of the driver lane so you can forget the "Hey, go get me a pizza" command.
I can't really see many reasons to buy a Tesla except its propulsion technology (i.e. big batteries). I doubt that's enough to compare it with the iPhone which was really more about software than hardware. Tesla software/user experience is not significantly better than a dumb car with carplay or just an ipad fixed on board. The only way for Tesla to win more market share is for the competition to ignore/defy the wanna be EV consumers.
