Well you kinda can't have 400kV in a highway.



Why would you? The lines go next to the highways, where they have always been.


Many 400kV lines run alongside highways.

Or you could put up wires on highways which means trucks can charge as they drive along. Germany, Sweden, the UK have been doing trials on this

"An academic study suggested the e-highway system covering all but the most remote parts of the UK could be completed by 2030 at a cost of £19 billion (£26.4 bn),"

In context that's about the same cost as Crossrail.


Interesting, if that becomes a thing then a lot of trucks could arguably do with a lot less batteries and thus waste less power lugging them around. Sounds like a win-win.
