I have this image in my head of a young kid standing stationary near the edge of the road with his back turned and a cyclist 50 ft. (yes, even if it were only FT. instead of YDS) encountering sever object fixation and panic, unable to make a decision whether to go to his right or his left before inevitably crashing into him.
If you did your responsible part, the only way you'd have run him over is if he was pretending to not see until the last moment, then turned and dove into your path as you passed by a safe distance away...OR if he RAN AT you and crashed into your stopped bicycle as you waited for him to clear your way.
Kids can be amazingly disrespectful, arrogant and stubborn. Its our responsibility as adults to NOT be these things when faced with decisions. After all, we've been around long enough to know better.
