I bet this means that people don't know how to get from A to B on a bicycle, rather than, you know, being able to pedal a bicycle in a straight line, and keep the thing upright.
For example: which streets are the best to take? What's legal/illegal to do? (sidewalks OK? "I DON'T KNOW? I'M SCARED TO RIDE ON THE ROAD/NOT ON THE ROAD") Where do I lock up this thing? What happens at night - do I need lights? What kind of light? What do I do if it start raining? Oh no? What do I do about my wheel - the tires not holding air!
These are topics not always taught to you... ever by... anyone. Especially the legal aspects of bicycle rights on the road. That leads to all sorts of arguments about what bikes can/cannot do and creates a horrible opposing relationship with cyclists and other road users. As a motorist, if you don't ride a bike as an adult, you may have NO idea what a cyclist is allowed to do on the road, but the same can be said about a cyclist that's JUST getting into riding a bike. They'll make all sorts of mistakes, and put themselves in bad situations, often angering other users of the road. How long is that going to last, until that bike is back in the back of the garage?
