How does wireless charging unlock this usecase? Robot arms exist?

I guess if you see the video on the linked post, you'll see what the usecase is unlocked. A neighboor city with a wireless charger station or a road wireless charger station can receive a self driving car above it, charge the car and with some kind of NFC do the payment and goes back.

The 3D rendered video of a car driving over the pad doesn’t really show anything unlocked. There are a lot of possible ways to build automated charging stations. This is not necessary tech for that scenario.

This is a lot better maintainable than a robot arm.
