> The concern about wireless inefficiency is very well-placed, however, in the case of electric cars.
I don't think so. For one, with EVs you are paying pretty directly for the charge and nearly 50% extra for the hassle of not plugging in the cable seems excessive. For a charging station it would probably be more profitable to hire someone to plug your car in instead of going wireless, even disregarding the setup cost.
But, more importantly, fast wireless charging generates heat. This is fine for the miniscule amount of energy in phones, but would probably pose a serious problem with the wattage involved in changing EVs. We're currently at the point of having charging cables with integrated cooling, the inefficiency of wireless would likely either cook the car or limit the speed too much to be viable ("charge your car as conveniently as your phone, in a meager three days!").
