Honest question but do you need a lot in terms of crash protection if the top speed is 25mph? Theoretically you should only be in a collision at roughly 25mph (assuming you're sticking to roads where the speed limit is 25mph like you should be).

It's certainly better crash protection than a pedestrian, a bicycle, a moped, or a Segway which seems to be the competition.

If you're on a 25mph road, you should assume a 50mph collision with a vehicle headed in the other direction.

Two cars of the same mass hitting each other head on at 25mph is the same as one car hitting a solid (immovable) wall at 25mph.

Regardless, a bicycle moving at 25mph being hit head on by a car moving 25mph is going to be (at best) comparable to this thing getting hit at 25mph.

Maybe _you_ can only go 25mph, the other vehicles have no such restrictions.

Again... same is true for a bicycle. Or a pedestrian. Or a Segway. We can argue physics and legalities but no one has seemed to touch the actual substance of my point, which is "does this thing need to offer better crash protection than its closest competitor, a bike?"

Two cars of the same mass hitting each other head on at 25 mph will be the same as one car hitting that wall at 50 mph. Remember p = mv and m1v1 = m2v2
