No point being driven to your destination only to be required to park the car. VW is working on it, developing existing systems to the point where you don’t even have to be in the car for it to park. It not only recognises the space, but will park in it better than you could, too.
In fact VW’s researchers shrugged when asked if the 20cm tolerances its self-parking system left down the each side of the vehicle are a bit rude. Someone else’s problem it seems, though don’t be surprised if you arrive back to your space to irate neighbours. Smartphone, smartwatch or key operation via holding a button means ultimately you’ll have control to stop the manoeuvre, so don’t lose your phone or keys when you’re out.
Production ready: There’ll be some legal issues to sort first, but expect it in the next few years.
