Crikey, that is so far away from the park-assist tight parallel-parking I've witnessed from Asian cars.. you tell it to park, and it drives slowly along the road until it spots a just-big-enough gap between two cars, and then it parks in the space for you. A couple of friends avoid parallel parking if they have to park themselves.

One anecdote was a friend had parked and another car parked too close in front of them, and they were basically stuck. And then they remembered the new parking-assist, and they flipped the switch and the car inched backwards and forwards and basically extricated itself by moving sideways like a crab!

Does the Volt get updates over-the-air etc?

My comment was assuming parking-assist was a solved problem! ;)

Parallel parking might be better, this was for reversing into a space

I noticed it did fine when two cars were present for it to use as a guide, maybe being able to use the cars as markers helps?

And as far as I know the car is "connected" via 4G (ODB data and remote controls are available in an online portal) but I don't think it's used for OTA updates (The last update I saw was for Android Auto integration and that was done by visiting a dealer)
