I was riding on a bycicle lane on a 2-lane 1-way street with cars standing still to my left for a traffic light 200 ft ahead. Right as I was passing a large truck a woman with two little kids by her hand appeared from behind that truck, running to cross the road without ever expecting other trafic could circulate on the bike lane. She was so close when she came from behind the truck that I only had time to scream really loud, that got her to stop and we just missed each other.

Another situation to add to the spider senses you need for survival as a cyclist in the US.
