Tesla Model S can now park itself
This is a pretty misleading headline.    s/drive/park/

That said, self-parking ability is still a big deal. Imagine when, say, 35% of the population gets them. You could have super-dense, extra-cheap parking lots for self-parking cars only. They could be packed extraordinarily tight, with no need for human valets.Your car's boxed in all the way in the back? It'll just tell the ones in its way to please get out for a moment. One car breaks down? That's probably rare enough that you can move the ones around it and bring in a tow truck or human driver.
