A big reason for that is so many places set the speed limit way lower than what is actually safe on that road. There's a couple 3-4 lane interstates I drive on regularly that are just about perfectly flat and straight for 70-80 miles and they have the speed limit set to 60. Traffic permitting you can easily do 90+ on those, the only thing that makes it dangerous is the other people on the road that are rigidly adhering to the 60mph speed limit scattered through all lanes. If the speed limit was set more appropriately I don't think we'd have as many problems with people speeding.
I’m afraid I have a hard disagree with conditions.
The road may be safe for higher speeds.
You don’t get to determine that at everyone else’s expense. I regularly drive roads where people average 15-20 over and they are not suitable for those speeds, it’s one fuckup away from a NASCAR-style pileup. People are shit judges of what is safe based on their perceived driving skill (99.999999% of which are horrible) and how important they feel leaving 5 minutes later than they should have for their appointment is.
Anyone significantly outside the average speed is the danger. Faster cars maneuver more abruptly and brake harder, by far creating more danger than those going even modestly over the limit. Too slow cars force those maneuvers and frustrate people making them drive like assholes because cars are an extension of ego for too many people.
Like I said, I’d be fine with Autobahn style limits, but there’s always someone who says fuck the rules because this road can go faster, and that’s why we can’t have nice things.
Edit: And this popped into my head after I wrote this - Even if the road might be capable of safely supporting 70-90mph traffic, cars are not designed to absorb that much energy when something goes wrong. No, "just redesign them" is not an acceptable answer. Changing to a structure that can better absorb higher speed impacts and keep the occupants alive increases weight and thereby reduces economy, and regulations aren't going to let that happen at all.
Issue being, people are always going to drive the speed they feel safe at. A sign, a rule, a law will do nothing to change that, unless you have a pig on every corner enforcing them perfectly. The way you change that is to ~not make the roads feel safe at faster speeds~. Fewer, narrower lanes and traffic calming features will do more for the issues than any speed limit signs will.
At the end of the day, a straight, flat, multi-laned road gives the feeling of safety at high speeds. I won't say this is THE intent, but at very least is a side effect of the multiple lanes in each direction. Lower that to a travel lane in each direction and a turning lane. Add some medians. Add a chicane or two. Suddenly people drive slower because that's what the road actually supports.
