If you're from a) Mars or b) America you might not have seen this particular Top Gear feature. If so, don't delay - watch it now. The Reliant Robin was a plastic bodied, three wheeled car that was, and still is, utterly crap.
Jeremy Clarkson treats us to a Reliant Robin history lesson, and several examples of its major flaw - it isn't very stable and is apt to roll when cornering.
If you don't laugh when watching this then you don't have a sense of humour - or you're the dork who reported Ling Valentine to the ASA.
