This is an absolute waste of weight and nothing more than a presser tech demonstrator.

Given induction's fundamental (physics) limitations, there's zero chance this will make it into a production vehicle.

The energy storage requirements and practical charging speed of a car are not remotely the same as for a portable electronic device such as a phone.

Human passenger EV charging will always be through a direct cable connection.

If you want something even faster, just do an automated physical battery swap and design the car's physical safety envelope and grounding systems around this additional access affordance.

Wireless charging is in production. Here's one example:

Wireless charging can be as efficient as wired charging:

Induction charging made it into production vehicles in the past [1], so always is a little bit too strong.
