Wow... Children can also drive cars, ride motorbikes, fly planes, perform surgery. That doesn't mean it's in society's best interest to let them without some training or examination beforehand.

The difficulty in riding a bike in a city doesn't come from having to control the vehicle. Danger doesn't come from the ability to maim someone with a bike. It comes from hugely complex set of rules, dynamic nature of traffic, high speed high pressure decision making necessary, sensory overload and fatigue, self control, competition on the road etc.

That's what you need to take into account to navigate safely.

But children do manage to ride bikes safely all over the world every day without any formal training. On the other hand, adults who have had training and are licensed to drive still manage to cause accidents.

Not in city centers on busy multilane inrersections, at least not in my country. We arent talking about riding a bike in a park or in the suburbs. And kids cause a lot of traffic accidents as well, regardless of their mode of transportation... Nothing will eliminate accidents. Training and systems can minimize it though.

Certainly when I was kid, bike and traffic safety was taught in school from 1st grade.
