My car will regularly detect speed signs that are adjacent to the highway, including those next to interchanges and exists. On many other occasion the camera detects signs from parallel roads and railroads, where the sign sits simply on the other side of a chain fence.
Naturally as a human driver I know that 170km/h doesn't exist on roads, or that a 30km/h isn't a legal speed for highway (except if there is road maintenance or accidents, which has their own contextual clues), but the computer don't know that. Trying to make computers understand context is the running theme of most failures in self driving cars.
The only way I could see a speed limiter like this would work is if there were a central control system with local knowledge of the road and those on the road, similar to how a subway control, airport control or rail way control works. cameras and satnavs is only good as an advising tool for an human operative.

Now you're getting, it's all about the control. Once they've got the device in what's to stop the government from saying your car can go 0 miles an hour if they decide it is necessary? It's all about control my friend, all about control.

- novok 4y agoIMO your 170km/h example is a sanity limit you could put into most computer programs. Similarly with GPS assisted general limits and monitoring. (Ex: your in belgium, and the national max speed limit is XXXkm/h, etc)
