What Car? says...
You've never seen anything quite like it, have you? What exactly is that car? Well, it’s the Citroën Ami – and technically it’s not a car, it's a large electric quadricycle.
Indeed, in some European countries the Ami can be driven by 14-year-olds without driving licences. Perhaps sensibly, UK regulations demand that you're at least 16 and even then you need a special licence.
