I'm completely lost here.

The amount of power you'll get is dependent on the Q factor of the resonant circuit. Using superconductors will allow you to get a very high Q factor and thus a lot of power received, even at a distance.
Using technology commonly available today, it's already possible to set up a fixed collector antenna (no superconductors, just common metals) near an AM radio station, then rectify the energy and use it to make hydrogen. (And then possibly use the hydrogen to power cars, but fuel cells are currently too expensive.) Or put the rectified energy back into the grid and charge EVs the conventional way.
So maybe we shouldn't think about putting radio energy receivers in cars yet. Instead, someone should set up rectifying antennas near AM radio stations and recover the energy to power EVs with. (Assuming, of course, that it is not possible to shut the transmitters down.)
