I almost crashed into my teenage son this afternoon.

Coming home from work, I met him on his bike coming the other way. I pulled a U-turn and started riding with him. Then we turned left into a new subdivision development in progress. He sprinted ahead. I sped up to catch him. He slowed while I was fiddling with my GPS. You can see where this is going. It was just luck that he had pulled to the right in the lane, while I continued past him in the center of the lane. Potentially, a very embarrassing situation to have to explain to the wife.
