Well this is the thing. And a lot of people realize parts of it, but I think it's easy to forget the bigger picture.
The fact is, and this is backed up with decades of research, the vast majority of drivers will drive at a fairly "safe" speed - based on conditions. Narrow road, hard to see around corners? People slow down. 4-lane divided road with no intersections and little traffic? People will drive 60, 70, maybe even 80. Unless they're worried about a ticket. And most of the time, the speeds that people naturally drive are pretty damned safe (except when we put schools and driveways on these major streets). This is why the Autobahn isn't a slaughterhouse. Incidentally, this is where the common "10 over the limit" behaviour comes from. Most speed limits are set artificially low as it makes enforcement easier in the "edge" cases - but traffic engineers know full well that 10 over that is just about always safe.
Of course you'll always get a small handful who drive like idiots, regardless of conditions or speed limits. There's not much you can do about these except enforcement. Which is precisely what traffic cops are supposed to be dealing with. Not nailing someone who is doing 35 in a 30 zone on a clear day with no other traffic when it's -30 outside and all the kids are inside.
It's also why there's no need to put "max 50, but 30 if the roads are slippery" on all of our signs. People for the most part slow down of their own accord. And the few that don't, either learn or pay the consequences.
Speeding just isn't the insane killer we make it out to be lately. Undue care and attention, is. But cameras and radar have gotten to the point that speed can easily be measured, focused on, and enforced - you'll notice that "speed kills" has gone from an occasional campaign to the primary discussion on all traffic issues, and this transition happened in lockstep with automated speed monitoring (and the legalization of photo radar, etc). Kinda the same reason why we now focus on holding your phone as being such a distraction, when literally all research shows that it's the
conversation that is the problem, not what your hands are doing. It's just easier to notice, and enforce, when people are holding their phone. It's got little to do with actual safety.
Much like this topic. It's safety theatre at best.
