This will repeat at some frequency dependent on the car.


Not if the car has shock absorbers.

Which of course all legal cars do.

well strictly not as MUCH if the car has shock absorbers. There are
few cars that are overdamped. Theres always a bit of 'overshoot and ring'

I'll be amazed if you can trigger it just by pulling the handbrake. It
would require a very large polar moment. I've only ever once felt it
getting out of hand on a bumpy road.


MM, I'll take you for a spin one day...;-)

However the point is well made that about 60% of the car weight tends to
transfer to the front under braking. for a 50/50 split before. So rear
wheels locked is never going to be that brilliant.
