Electric bikes are a new measure that need to be evaluated accordingly, an added complication because it has a motor. But when talking about pedal bikes it is absurd to expect them to follow rules meant to cars. Bicycles are a hybrid between a pedestrian and a vehicle, and can operate in either mode: a slow moving bicycle is a pedestrian and should be able to go on sidewalks and anywhere else a pedestrian is allowed; a fast moving bicycle is a vehicle and should be allowed anywhere a vehicle is allowed. Some countries already have this on mind when creating their rules, so bicycles are allowed to do all that stuff, the others need to change their rules.
