So, if I put a pro rider on a bicycle you're cool with me having them scream around crowded areas?
Traffic regulations are fundamentally about tail events. Most of the time, vehicular traffic is boring.
The right metric is kinetic energy. But, it'd be unpopular for speed limits to depend upon vehicle mass. Or, in the case of bicycles vehicle and rider mass since the rider mass isn't negligible.
Reckless endangerment covers the case of pro-riders being idiots. Classification of the vehicle should rely on the vehicle's properties instead of the operators capabilities.
However, that shark is jumped as soon as the classification criteria involve operator-dependent properties like maximum speed of a bicycle. It has no operator-agnostic answer.
