into a brick wall, for example. driver safety needs to be guaranteed whilst causing as much damage as possible.
******* stupid thread. Can't even spell.
TSR reps people like this?
25mph I'd guess, in a new car with a 5* NCAP rating.
5* NCAP is roughly safe to drive at ~30 into a brick wall but why would you want to and why would you take the risk?
err how about not crashing and keeping the working car?
300mph if you're Richard Hammond.
How fast was Clarkson going when he crashed into that wall while driving a lorry?
10mph repeatedly for a few hours.
depends. there is no 'safe' speed to crash a road car really - too many variables. If you start putting in cages, harnesses, HANS and helmet, reinforcements etc, then it becomes more feasible, but it is inadvisable to crash a road spec car at any significant speed.
If you must destroy the car, just beat it with a sledgehammer, then set it on fire (but not when you're in the car). Much safer.
It isn't safe to crash a car. Duh.
