    Yeah, I’m sure they can drive safely at 200km/h at a race track. There’s no way to drive safely above the speed limit on a public road.

      There’s no way to drive safely above the speed limit on a public road.

      If you’re driving a well maintained regular car in good conditions you absolutely can drive safely above many speed limits. If the speed limit was set at the true limit of safety nothing but the best handling vehicles in the best of conditions could drive at said limit safely, and this is clearly not the case for the vast majority of speed limits. Instead most traffic can travel safely at the set speed limit in less than ideal vehicles and in less than ideal conditions, so logically there are going to be situations where it would be safe to drive above said limit.

      Consider too speed limit changes. In my area there have been a few roads recently which have been lowered from 100km/h limits to 80km/h. Nothing changed about these roads except the speed limit signs. Why was it possible to drive safely at the 100km/h limit one day but not possible to drive safely at the same speed on the next day? Another road several years back had its speed limit changed from 80km/h to 90km/h. Again only the signs changed, so why would it be unsafe to drive 90km/h there one day when that would be the speed limit the following day?

        As with everything we do, there is a subjective element to setting limits, but it’s definitely not as arbitrary as you are suggesting. Maybe they reduced one limit because there were too many accidents, and maybe they increased the other because they finally got the signal pattern working as intended.

        Risk assessment is incredibly complex. It might be perfectly reasonable to drive 110km/h on a given road most of the time, but frequent use by large farm equipment could necessitate a lower speed. Or, maybe adjusting traffic on road x decreases accidents on road y.

        We are still learning how to produce vehicles that reliably compensate for variables like friction, or human reaction time. The implications of even these two simple things seem to be completely lost on most drivers: with a tiny bit of rubber touching the asphalt, we happily drive around in inconceivably heavy vehicles at rates where it’s very easy for an event to begin and end before we even suspect something is imminent.

        While I’m here: turn your lights on when you start your car, turn into your own fucking lane, always move over if someone is behind you in the fast lane even if you think you’re going “fast enough” (someone could be bleeding out, seriously), don’t pass people on the wrong side, and finally: stop trusting the meat in your head so much, our brains fuck up all the time, so in addition to driving defensively wrt external factors, consider how you can set yourself up to succeed if something unexpected happens internally.
