E-bikes have a speed cap so they don’t get classified as motorcycles, which would require insurance, registration, and extra licensing to use on public roads.

The problem with dynamic speed caps is that they fail in very dangerous ways. If you’re on a freeway but your GPS thinks you’re on a residential street, you’re suddenly going much slower than surrounding traffic.

A simpler solution would be to actually enforce traffic laws. It’s only a tiny fraction of drivers who endanger the public. The sooner we identify them and get them off the road, the safer we’ll be.
