: A license could accomplish two things:
:
: 1. A bicycle rider would have to know the laws appicable to bicycles
: in order to obtain the license.
:
: In other words, kids too young to understand the laws would be barred
: from riding bikes. Intensely bad idea.

In Germany, the kids have to take the cycling course at age 10. Is that too
young to understand? No, it isn't. They assume that kids younger than that
are not riding in the street, anyway.
