My brother lost his license like that. I used to work at Burswood for 3 1/2 years & I seen them on top of that bridge a few times, during all different times of the day. Used to get stared at all the time at 4 in the morning as I drove past them. Occasionally just a car, sometimes 2 bikes, sometimes both with two on the bridge with radar guns for both directions & the bikes waiting on the down ramps.
