Do roll-cages make road cars safer? Cars that are expected to get a battering: rally cars, demolition derby cars etc generally have comprehensive cages rather than air-bags and crumple zones yet I'm sure I read somewhere that cages in ordinary road-going vehicles can be dangerous in an accident. Can anyone elaborate as the two ideas seem to contradict each other. I'm thinking of full roll-caging my car for safety's sake but is this a bad idea for road-only use?
Thanks
