how much space we could save on highways if we have electric self driving trucks doing mile long convoys - self driving trucks can have short "safe distance" between them.
radars can be dual use - as radar and as communication device. 60ghz wifi has 10gbps speeds, line of sight only, so excellent for connecting columns of trucks.
And then you still have each truck with an individual ICE, how is that better than an electric locomotive? (Yes I know, the rail network isn't nearly as electrised as much of Europe)
Still, I love seeing the swap bodies rolling up the passes in Austria.
That would literally fix nothing. Moving long range trucking to electric rail actually does.
Hmm yummie! Even more tire dust of extra fine grade. Black marmalade. Tar Star Wunderbar!1!!
Not to mention more wear out of the highways.
