The father in this case has a small baby and his 3 year old with him. He made a judgement call that I’m sure other parents would have made, who are we to second guess him?
The law would tell the driver of a car to be in control of his/her vehicle at all times so why is it not the same for a bicycle?
Never said it wasn’t. Though rules could vary (in AZ muli-uee trails right of way goes to horses first then bikes, pedestrians having the shortest stop time have to yield to everything).
But again, the laws of physics don’t. You have GOT TO be aware. Assume other traffic doesn’t see you, won’t yield, and will your kid over if the chance occurs. So don’t let them. Don’t let your kid be a position where the law their only defense. Put physics on their side.
