When Sir Clive Sinclair revealed he was working on an electrically powered pedal car known as the C5, it was widely hailed as the next big thing.
Not that long after, one was spotted in filthy conditions on the Leckwith roundabout in Cardiff. It was small and exposed, with the driver looking petrified as lorries whizzed past with spray shooting up off the road and into his face. You kind of reasoned, then, that the C5 wasn’t going to prove a winner, after all.
It doesn’t always have to work out along those lines. Sometimes the hype is justified.
