Speaking to the US as a whole on traffic law is hard to do. E.g. in Washington it is absolutely legal to exceed the speed limit to pass someone on the highway, in California it isn't. In California it's illegal to sit in the fast lane, in Minnesota it's not. In Minnesota you can turn right on certain reds, in DC you can't.
Regardless of where I've travelled in the US I've yet to see someone get pulled over for travelling in the passing lane (though I know it to obviously be a thing just not lucky enough to witness it). I thought for sure I was finally going to see it in Texas with this person doing 10 under in the left lane but the trooper just passed on by to their right.
> two vehicles driving next to each other slowing gaining on another to overtake is also creating a dangerous road situation
Then perhaps you shouldn't pass if it's not safe to do so. My problem with everyone in this thread and who is against speed limiters is: the subtext is that they want to go faster than the speed limit so they can arrive faster. It's simply the fact that people are willing to engage is an extremely dangerous activity multiple times a day so that they can save a few minutes a day. The idea that people should have the right to go dangerously fast because it's simply more convenient for them is a psychotic proposition to me
Most US states aren't anything like Virginia. I just did a road trip across ~20 states and in none of them did people in cars (as opposed to semis) actually follow the speed limit on the highway. Most states had ~8 over as the normal speed, none were less than 5 over.

No one is saying anything about dangerously fast driving. In most US states speed limits are set with the understanding that a significant portion of drivers will drive 5 to 10 mph faster than the speed limit and not get pulled over even if a cop sees them. In those states driving at or below the speed limit is actually more dangerous because you're creating an obstruction that other drivers who are following the expected driving patterns have to adapt to.
(Again, from what I understand that doesn't apply to Virginia, which would be why your experience differs from most here.)
Only applies to two-lane roads.
