Not true when a "fast bike" collides with a stationary object such as an opened car door, or collides with a vehicle pulling out or turning left in front of the fast bike. I suspect bikes being ridden fast may be especially vulnerable to just these type of collisions due to driver miscalculation of a "fast bike's" actual speed.
