> It's really a non issue. 25kph is an unreasonably slow limit. The energy levels involved in a bike crash simply don't compare to the potential for damage in a car crash, in part due to the lack of mass.

If I crash my car at 50 km/h collision speed chances are quite good that I'll be sleeping in my own bed that day.

If I crash my bike at 50 km/h collision speed, I'm lucky if I survive.

Energy levels are irrelevant. When I'm riding a bike, my body is the crumple zone.
