How on earth would you measure someone's pit lane speed!?

Ok... that would mean that you have to calibrate yout throttle before every race to ensure they are all equal at all times which would be a nightmare as you will always get someone saying "I had to squeeze it half way for the car just to move". Not to mention different magnet strength in each car which would mean different throttle threshold for everyone to go below certain speed.
