Good for you, didn't put out your hand, the big mistake too many riders make. When I've gone down flat like that, I push my helmet into the pavement as I slide. Cuts down on the road rash. Need a new helmet anyway. I don't pedal over speed bumps either. I call them out so Stoker can raise her butt. Nasty of them to put a speed bump in a sharp turn. I'd complain to the city. Good chance of sliding out even if you didn't pedal.
