Great idea from Audi but there are so many problems with it.
It's illegal to leave a car on the road with the engine running while it is unattended, must be illegal to let the car drive off on it's own.
How you deal with paying for the parking.
How do you find it when your phone goes flat?
How do you summon it if your signal goes?

And as for the stress of parking - an unmanned car driving around the car park at that speed would cause me a lot of stress!
