How about the number of children who are hit in school zones by parents driving their kids to school? I started walking to school when I was 5, this included crossing a fast moving creek and along roads without sidewalks in the 1970s. The only person I ever knew who was hit by a car was a friend when we were cycling to school in grade 9 and he ran a stop sign.
Parents today have become so overprotective and do everything for their kids, except teach to be accountable for their decisions and actions, no wonder they are lacking independence.
