Enforcement should focus on the speed outliers, less on the posted limit itself. If the speed limit is 65mph, but all traffic is moving at 75mph, then I'm going to drive at 75mph. The most dangerous drivers I've seen are those going 30mph or more faster or slower than the rest of traffic. Yes, the problem is that then makes enforcement subjective and that itself can lead to abuses. But it's a sensible approach in the short term.

Because of my morning routine, I often end up getting on the highway around the same time as this other driver who merges into highway traffic at 35mph, and several times they've nearly caused a crash. They're as much a menace as the idiots weaving in and out of traffic at 100mph+.

In many cases the state and local police are always speeding here as well, going the same speed as everyone else (regularly 15-20mph over the limit). Fortunately I do often see them pulling over the aforementioned idiots going 100mph+. Though I wish they'd at least give warnings to the people going dangerously slow as well.

Same. A little "ma'am, I'm not asking you to floor it, but at least try and do a little better than a loaded garbage truck" would go a long way.

Also, many municipalities have stupid or predatory speed limits. Many town roads have a natural safe 40-45 mph limit, yet some coalition of neighbors got together once and convinced the town to drop it to 25-30 mph because "cars just go by way too fast on that road!" Either that or it's a small town on the way to a tourist spot that drops the limit from 55 -> 30 for a 1/4 mile segment behind a blind curve just to rake in tourist dollars through modern highway robbery.

Virginia has built a reputation for tighter highway speed enforcement than most other places. There are officers out there enforcing as hard as the judges will let them. Now Virginia will put speed control devices in the cars of repeat offenders. Like breath testing ignition control devices, these will save lives and the offenders will pay the cost. Just another step toward better road safety for Virginia. They’re a good example for other states to follow.

I expect this to increase the number of vehicle accidents since it is forcing people to drive at speeds well below the well established principle of the 85th percentile. We could have improved safety from increasing speed limits to the 85th percentile rather than trying to artificially slow down motorists. Higher speeds mean cars get off the road faster, which means there is more distance between them. Collisions only happen when the distances between vehicles reach 0, and higher average distances inhibit collisions. Trying to force people to drive slower has all of this logic work in reverse, causing more collisions.
