Not because I couldn't get my foot out.
i agree. i have never fallen cause i couldn't get my foot out. i fell 2 times, once while turning really slowly i learned what toe overlap was.the second happened on the first day i got my bike, i rode too close to the side of the road, slipped into the grass and instantly fell.
i have lost my balance a few times but i always seem to get my foot out in time to catch myself. "knock on wood"
