I might be considered a bit of a luddite when it comes to automated sensors and navigational aids on private cars – I can never see the point of taking the human out of the loop – don’t believe the dumbing down can be net positive.
But this road-train idea I like. Totally guided – hands-off / brain-off freedom as in a train when linked to the lead vehicle, but private motoring when it’s the motoring flexibility and freedom you want. Can see the efficiency working if the cars themselves are hybrids – with performance when you want it.
Guess there must be a few failure modes to work out before this can go live ?
