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.
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.
I hate people like you on the roads. You're not the one who decides what's the safe maximum speed on the road is. If you think you can arbitrary decide that some speed limit is too low and you can drive faster you're wrong and shouldn't be on the road at all. If we had less people like you on the roads everyone would be safer.
If speed limits are indeed set at the true safe maximum for all vehicles and all conditions then how can you travel safely at said speed limits in your car, which I would wager cannot corner as well or stop as quickly as a top end sports car?
If it's a maximum limit to what's safe, you can say anything at or below it is safe. They don't set the maximum at a value that is unsafe for some vehicles.
Indeed, at least for most modern speed limits. That was intended as more of a rhetorical question to lead the person I was replying to towards noticing speed limits are typically set with a wide safety margin, and not actually at the limit of what can be safe in good conditions.
I'm not saying all speed limits are set perfectly. I'm saying it's not up to you to decide which ones are 'safe' to break. The driver that think they know better than everyone else are the most dangerous ones. Even if you think the limit is set tol low just follow it, ok? Is it so hard?
Say that to start off with then rather than "there's no way to drive safely above the speed limit on a public road", because there clearly are roads where it can be safe to drive above the speed limit.
Great, as long as we agree you should never drive above the speed limit I can agree that there definitely are some roads where the speed limit is set below the maximum safe speed.
There are a lot of streets without a speed limit in europe. People are told to drive around at least 130 to not hinder traffic. Most people go about 140 or 150 if the roads are free. Speed lane is usually about 160
No, not a lot, only highways in Germany AFAIK. Where I live the limit is 120 so 150 is always over the limit. Road fatalities in Germany are the same as in my country because in Germany you also have idiots driving 200km/h. What you have to do is adjust your speed to the conditions. Depending on how the roads are build the limit will be different but if you're driving 50km/h faster than everyone else you're creating dangerous situation. Same if you're driving too slow obviously.
There's also the Isle of Man, but it's an unusual case in its own right
