I'm not talking about push scooters, muscle operated bicycles or pedal assisted e-bikes with a power rating below or equal to what an average person delivers. This is a discussion about motorized vehicles with more powerful engines that can operate at speeds in excess of 15 mph. At 25 mph you can definitely kill a pedestrian or knock another cyclist and injure them. Bicycle licensing is unnecessary. 1/2 * (100 kg vehicle + occupant) * (45 mph)^2 = 6328 J ~7×10^3 J = Muzzle energy of an elephant gun, e.g. firing a .458 Winchester Magnum[90] https://en.wikipedia.org/wiki/Orders_of_magnitude_(energy)#1_to_105_J https://en.wikipedia.org/wiki/Orders_of_magnitude_(energy)#1...
