On the road: Citroën C4 Cactus Flair BlueHDi 100 car review – ‘These rubber panels are the car equivalent of a nappy’

The implication is that you can have little accidents with no harm done

I noticed the Citroin Cactus before I ever drove it, for its natty sides: rubber panels they call air bumps, which are replaceable. I've thought about this a lot. The implication is that you can have little accidents with no harm done, so the panels are the car equivalent of a nappy; yet, until all other cars have replaceable side panels, it is unclear to me what you'd be able to prang into. Trees, I guess: except it's not four-wheel drive and it doesn't look remotely like a car you'd want to take off road.

Silliness, we call this - like wearing a flak jacket on Oxford Street. The panels also managed to react with the stereo, so that the sides seemed to vibrate even at pretty low volume. If you are trying to impress the laydeez, this may be part of the point; it didn't impress anybody I drove past, thumping with Adele.
