Re: Carbon neutral
Or since you like trains... maybe a catenary over certain sections of the motorway, obviously not at junctions (but you don't need it to be constant).
Nice idea and you aren't the first to think of it, see:
Catenary trucks still stand chance in race to decarbonise road freight - researcher
Highways wired with catenary lines like a railway: is this the future?
