I get winter, do you think none of that exists here? The mistake is assuming it has to matter.

you are too fixated on the idea that powered road= vehicle gets power from the road using direct contact with the road. If that is the best way then OK, but look at



is this pic of an electric trolley from Russia rolling on an road that has not been cleared of snow yet?



is this a plug less car charger where the charger is on the ground while the car bottom is floating above it?

I am not advocating a particular design and there might be some that won't work with snow like those electric racing cars when I was young [Link: s-media-cache-ak0.pinimg.com].

but there are countless way that could easily work even in the worst weather.

I will let engineers decide the best.
