Electric roads power electric vehicles

For a long time, people have talked about the concept of roadways that can provide electricity to the cars, trucks and busses running above.  While a cool idea, I always thought the economics of this didn’t make sense and it wouldn’t be implemented in our lifetimes.  At least on a small scale, I’m proven wrong.  South Korea has equipped fifteen miles of city streets with just such a system – underground cables that charge EVs that are either parked or driving above.  It’s cool to see this technology progress…but I still question whether it’ll be widely adopted this century.  It requires massive public infrastructure investment and commitment to this transportation technology.  In the US at least, those are two things that we are so incredibly far from, at least politically.  Maybe some other country can pull it off.  I can see this working out well with only major roads having this charging capability…the EVs would still use a small battery to power them on trips off those main arteries.
