If you’re relying on GPS speed limiting, you’ve already failed at designing a safe roadway. It’s a bandaid at best. Besides, how are you supposed to enforce the usage of GPS speed limiting on every bike? Regular bikes are just as capable of significantly exceeding, say, a 15mph (25kph) speed limit as e-bikes. It doesn’t make sense technically, logistically, or politically in the vast majority of places.
Much more tragic on average per occurrence, of course. But, I’d be willing to bet that the chance of falling down that slope is way higher than being hit, and thus the “average damage over time” is far greater for falls than collisions. People are really bad at comprehending risk. (See: dying from a shark attack or lightning strike being more common fears than dying from falling down the stairs.)
It feels wrong to reduce human lives to a numbers game, but that’s what traffic engineering is. If there’s a budget, it has to be a numbers game at some level.
