I feel like I saw this Chinese elevated bus concept previously - perhaps at the drawings stage of design, but now there’s a scale model to show how it really would work.

It looks incredible, wonderfully futuristic, and it’s a brilliant idea. BUT, I do get the feeling it wouldn’t work with human beings behind the wheel of the cars. What if someone has to get out for a second - or pull over? What if there’s a crash underneath it. Where do the lorries go?

It’s a genius piece of thinking, but I’m surprised they are going to trials as it doesn’t seem entirely practical. I could watch that video over and over though.
