I would add “passive aggressive” drivers to your list of the dangerous.
I used to take a 50mph road, with one lane in each direction. Many times I’d see folks doing under the limit and when being passed, would speed up to block.
Not just a couple mph here, which often happens when being passed which I attribute to a kind of pack mentality that makes groups want to keep up w/each other.
I’m talking flooring-it speeding up.
Lots of head-ons on that road, for which would I blame the passive aggressive more than the aggressive.
I don’t mind those who want to be slow and safe, but I absolutely detest those who feel they must “punish” those that don’t follow their “model”.
This is one reason I now have a dash cam.
Most people I see do that do it to chronic tailgaters who dont seem to get that driving 6 feet behind someone at 70mph pisses people off
