The problem is that a lot pf times the limit is a joke. It needs to be set what is actually safe, not arbitrarily low to create speed traps or whatever. There’s really no reason an interstate that’s more or less straight for 100 miles should be limited to 55/60. People are not going to stick to that because they can safely go a lot faster (depending on traffic obviously) but then you have others who will rigidly adhere to the speed limit while ignoring proper lane usage. The combination of the two types of driver create dangerous bottlenecks where you have congestion and people weaving in and out to get past slower drivers.
Fixing the speed limit would at least eliminate the issues caused by people using as a justification to drive slower than the rest of traffic in whatever lane they want. The next step would be to enforce properly keeping right if you are not passing which is what is responsible for a lot of the dangerous congestion people encounter on the road.
As for what Ford is doing either way it’s stupid but if they’re going to do that why not just make the system limit the top speed to whatever the current speed limit is instead? You know, actually fix the “problem”.
