I use flashers for tailgaters. If I cannot see their headlights and/or the road directly behind me in my rear view, they're too close. I hit the flashers or about 4-5 rounds. Almost without fail they back off immediately.

Because tailgaters fall into one of two categories...1-intentional, or 2-not intentional.
If 1- simply do not realize how close they are, flashers alert them, they have an “ah..” moment and back off.

If 2- I do the same, they respond by either backing off, or passing me.

In both scenarios I do not alter my driving because someone is inattentive or aggressive. Win-win.

In the extremely rare occasion none of the above work, I choose a good clear section of the next lane and move over when it’s safe.

And for Pete’s sake, there are literally 20+ items that are far, far more important to traffic flow than who is in what lane. It really is one of the least important things affecting flow.

Like merging, or using a lane that’s ending, or not stopping in a crosswalk, or how far ahead drivers look, or how often they check their mirrors.

People insist they are very good drivers when they do not understand the actual question.

Don’t confuse “operating a vehicle” with “understanding how traffic flows”.

Last thing, what follow on training has anyone had aside from high school era drivers ed?
And dont count “traffic school” for a infraction.
