(Showing my age again. Kids today don't ride bikes to school. All you gotta do is look at the lonely single bike rack at elementary schools. In my day there were lots of racks festooned with bikes. These days when I pass a school, there's a long line of moms in SUVs with the motor running talking on their phones.)

In the USA. But in plenty of other places they do. In fact, at the bike rack of my sons school there is too little place, so some of them overflow onto the school yard.
