My bad I didn't see that proportion thanks for clarifying. As more than half are already going over the speed limit then there is indeed a more systemic problem. I thought it was about say 10% fringe that go with heavily modified bikes. I'm not sure more tech would help though, rather than fines with explanation of the risk until people do start respecting the limit. If people are unable to respect that and it causes more accidents, then yes ISA on e-bikes, cars, everything causing accident on the road.
