Volvo reveals the inventive self-parking car

Manufacturers have often sought ways to make parking simpler; specifically parallel parking. Parallel park assists have been around for many years, allowing the driver to find the space and let the car park itself. These systems, however, remain complicated and time consuming, and while clever, not particularly practical.

But Volvo has another idea. They've created a car that finds an open spot in a traditional parking lot, drives to it and settles itself, without the driver needing to be in the car. Then, upon return, the car will be ready and waiting outside the door. How's that for valet service?
