I hired an annoying little Renault a couple of years ago. It would quite happily park either parallel or end-on, did a fairly reasonable job of it too. I didn't use it much, because it's almost as easy to park a car that size manually as it is to hit a couple of buttons :P. I think the difference between that and Tesla is that the Renault still wanted me to put the (manual) gearbox into reverse and use the accelerator to move the car, it was only controlling the steering wheel.
