That negligible difference is actually a fairly large one once the physics of inertia and impacts gets into play. The energy, and therefore the damage, is exponential based on velocity. That ≈6.6km/hr difference increases damage by a lot more than you may suspect, and pedestrians don’t generally wear helmets and pads to protect themselves from impacts.
No exponential. Geometric. Squared. Energy is E=mv². At a speed of 60 freedom units you’re going factor 2.4 times faster than at 20. The energy will be factor 5.76 times higher. Or 476% more if you like.
The word exponential has a specific meaning. It doesn’t just mean really big.
That’s a fair point. But I’d assume most of downtown New York City has of speed limit of 25mph anyway. So Class 3 riders shouldn’t be going above that, regardless of what their bike is capable of. Whether you drive a Lamborghini or Toyota, you’re still obligated to follow the same laws (horrible analogy, I know).

It’s geometric, not exponential. Going from 25 to 28 freedom units is factor 1.12 and v² increases by factor 1.2544 or 25%.
But at 60mph if you crashed into a wall you’d vaporize instantly. Because exponential.

So vapor. Yeah my first post was supposed to be sarcastic by the way.
