Just an observation about young parents in my neighborhood. They go for walks and walk properly against the traffic flow. However they bring their children with them on bikes and tricycles. Those young kids are learning and getting used to riding on the wrong side of the road. I wonder what side those kids will ride on when their parents are not around. Will there be a training period where the parents correct the habits instilled in their kids?
Lately I've wondered about the old wisdom of continuing to insist pedestrians walk against traffic.
