Tesla is developing a wireless charger. So these could be embedded in the street negating the need for cords.

    I am assuming you're assuming inefficiencies in wireless charging over wired charging. One provider looking at this technology finds wired and wireless VERY close to one another in efficiency, with wireless possibly being even MORE efficient.

    "Wireless charging for EVs is considered as efficient and fast as charging with a plug. For example, most EV plugs have 80-95 percent efficiency ratings. According to WiTricity, a leading provider, their wireless EV chargers achieve 90-93 percent efficiency. " source

    I would be interested in that if done by anyone else than elon. I wouldn't put it past them to have made that proposal to kill public transit or something else. Like they already did with the dumb tunnel that was canceled now.

    Yeah, and most wired charging for a modern EV and charger is on the upper end of that scale.

    The wireless charging being that efficient is reliant on the ground never being dirty or wet, the charging coils on the car being very low, and the car being perfectly aligned.
