For example, it's hard for them to see an accident situation developing. They may focus only on things that interest them the most. For example, an ice cream truck across the street may be much more interesting than the dull brown car coming down the street. They often believe that grown-ups will look out for them. They may think that because they can see the car coming, the driver can see them, too, and will know they are about to cross the street from between two parked cars.

In fact, peer pressure is probably one of the biggest barriers to teaching safe cycling to children. Many accidents happen when a child on a bike takes a chance and another child following takes the same chance and gets hit by a car. Parents must realize that untrained children have no safe place in traffic, and the job of teaching children how to ride safely goes along with buying them bikes.
