The first time i read a shitpost about that, i thought the same thing as you did, "haha that's a funny and brilliant way to remind us that trains exist and are great".
Then i did some research and reading and i suggest you do too; you'll learn that rail freight is already extremely developed pretty much everywhere; cheaper than road freight; and when trucks are used, it's not because some fucker wanted to burn oil for fun but because rail didn't work for that.
So yes, electric trucks are, in fact, not a dumb idea.
Sure it would be even better to engage less in our ultra consumerist society and buy less random garbage so that eventually results in less trucks on the roads - and less trains on tracks, because in the US, one of the reasons why passenger trains suck so much is because the tracks are saturated with freight trains, whose traffic has a higher priority.
You're welcome!
Building roads is a lot cheaper than building railroad tracks.
