In the UK, all vehicles on the road are required to abide by the highway code. Yep, that means bicycles have to follow the same rules as drivers.
In the 1990s, schools in the UK ran cycling courses to ensure that children as young as 9 were already learning the highway code, and would be able to cycle on the roads safely. The London police to this day continue to run cycling courses to provide the same level of training.
I can't speak to the rest, nor in other countries, but in the UK, it is absolutely not foolish, but actually required by law, for cyclists to follow the same rules as drivers.
