I saw this cyclist coming in from my left and sensed he was not going to look or stop before the stop sign so had back off. I think he head my brakes grab (disc) as he looked up at the last moment and braked as he crossed the stop sign. You can see in the video both brakes applied hard.
At least slow down and check for traffic at stop signs if you want to yield to them; just barreling through could be nasty.
This was the at the intersection of Stevens Street and Attfield Street, Fremantle.
