Some of the replies to you are focused on “nanny state” objections. So, how about a private sector solution here? Offer people a significant reduction in insurance for installing a speed governor that limits speeds to legal limits?

I don’t think it’s unreasonable to try and reduce speeds. Speed kills, and that’s a fact. A lot of the killing is externalized as well.

I’ve said it before, but people who drive public streets like a track should either get themselves to a track, or internalize their risk-taking by buying a motorcycle. As a motorcyclist, I’m very aware of safety trade-offs I’m making. Oddly enough, not being inside a steel cage is a pretty good reminder to keep safety very high on the list of things I think about while riding.
