Which, IMO, is one of the reasons why I think speed-limit based speed limiters are a poor idea now. (I didn't mention much in my other post at https://news.ycombinator.com/item?id=40919908)

Personally, I think this (speed-limit aware speed limiters) are going to trigger Congress to either fast-track legislation to disable them. Specifically, once the general public is aware of what's going on, they will stop buying new cars and car manufacturers will push on Congress.

I also think the legislation was written by someone who is very naive about engineering. What I remember is they tolerate a 10% error rate. If 10% of the cars are going too slow during rush hour, it's just going to create a major traffic jam.
