> Want safety? How about a Tesla that is electronically incapable of speeding. That would be unsafe in many situations. If the flow of traffic is substantially above the speed limit--which it often is--being unable to match it increases the risk of accident. This is known as the Solomon curve [1].

Ok. Electronically incapable of driving more than 10% faster than other traffic.

  How do you know which traffic is "the other traffic"? So basically - there's no top limit.

> Subsequent research suggests significant biases in the Solomon study, which may cast doubt on its findings With the logic presented in the theoretical foundation section, it seems that the safer move would actually be slow down and match the speed of all the trucks and other large vehicles... which won't happen. Matching speed sounds great, except there are always people willing to go faster and faster. In my state they raised the speed limit from 70 to 75, it just means more people are going 85-90. How is that safer?

  To address your last paragraph, everyone going 85-90 is less safe than everyone going 70-75, you are correct. However, you individually going 70-75 when everyone else is going 85-90 is less safe than you going 85-90 like everyone else in the exact same situation. >there are always people willing to go faster and faster That’s why no one says “go as fast as the fastest vehicle you see”, it is “go with the general speed of traffic”. That’s an exercise for human judgement to figure that one out, which is why imo it isn’t a smart idea to have the car automatically lock you out of overriding the speed limit.

  People are going faster because they felt it's safer, not because of the speed limit. You can design roads that cause humans to slow down and be more careful.

    Or you can just set the speed limit appropriately, in accordance with sound engineering principles. A radical notion, I guess.

A self driving car obviously needs to be aware of other cars on the road. I don't see any reason why the car couldn't observe other cars, see what speed they are going at, and refuse to go faster than the rest. A car that refuses to do 120mph when all the other cars are doing 60mph in a 50mph zone should be trivial. (Trivial if the self driving tech works at all....)

  You're getting downvoted for this comment apparently, but I'm still of the firm belief that we will never see full autonomous driving without some sort of P2P network among cars/infrastructure. There's just too much shit that can't be "seen" with a camera/sensor in conjested traffic. Having a swarm of vehicles all gathering/sharing data is one of the only true ways forward IMO.
