Safe speed varies with weather, time of day, and even the flow of traffic. There's no one number that's going to apply to a given stretch of road all the time.

- RandallBrown 6y agoProbably not feasible to do this for every speed limit sign in the country, but there are already variable signs on places like mountain passes that change with the weather and traffic.

A truck or an older SUV will have a far worse breaking distance and does not corner well compared to any sports car or sedan. So even assuming you a perfect situational analysis, you still could not post an exact limit.
- nitrogen 6y agoSome freeways have two limits, one for semi trucks, one for the rest of traffic. Something like that could be extended to lanes, along with prohibitions (which already exist) of towed trailers in faster lanes.
