It’s definitely a trade off but both options have a lot of real world concerns. If safeguards on the wireless pad fail you could easily cook an animal or start a fire. The bottom of the car now needs to be metal free to allow this to work. Distance matters which means if it charges your Porsche it might not be able to charge a Rivian and certainly not with the same efficiency.

I also frankly do not believe the 90% efficiency claim because it seems so much higher than any other wireless charging I’ve heard of.

This seems like one of those things that seems cool but is not generally practical. As a convenience for wealthy Porsche EV owners, sure. As a general purpose charging solution? I doubt it.
