That /is/ how "we" do it with trains. The difference is that long-distance truckers generally live in their cabs for weeks on end, so they can't easily hand it off to another driver.

Ok. So then the lorry and the driver stay behind and the lorry/payload get switched. But apparently there is no such need for speed for road transport and otherwise they would use a plane?

Long distance trucking will be the last to go electric for a variety of reasons, weight being one of the biggest. We're mostly talking local delivery here.
