I don’t know what you really mean by acceptable, but there are plenty of roads with a 65 mph speed limit where 80 miles an hour is perfectly safe, and there are of course plenty of roads with a 65 mph speed limit where 70 mph is and unsafely fast. And there are road conditions in all of those roads where 45 mph would be on unsafe. It is difficult to make blanket statements about what a safe speed is knowing nothing other than the posted speed limit.
To put the same point in a different context, remember that it wasn’t really that long ago that there was a national 55 mph speed limit, and many of the same interstates that used to have a 55 mph speed limit now have an 80 mph speed limit.
IMO roads with 80 MPH speed limits are much safer. Even the crazy folks don’t go much over, so you don’t get a huge delta in speed, which is a lot more dangerous than any absolute number.
There's stretches of flat, straight-ish interstate in the US that continue for dozens of miles with near-perfect visibility. Sometimes, there's no traffic. Go 120 for all I care, just slow down when you're near something.
Or the road is in good condition.
Or that your tires are rated for that speed (T or higher).
That's the wrong approach for a left turn.
> Imagine actually having protocols around traffic flow, and following them!
Like limits on the magnitude of vehicular velocity?
In Germany you get fined and ticketed for it. In NA you don't. It's that simple.
I almost want to become a cop just so I can write tickets for this.
