Not a slow driver in most cases, many slow drivers - all who want to go faster but cannot. There is just so much traffic that you can't go faster, and neither can the person in front of you.

I used to drive 20 under all the time (I achieved 57mpg once doing that) - but since this was an empty rural highway the few cars that were around saw me well in advance and moved over and passed without a problem.

I am surprised that research backs you up... my guess had been that the majority of tailgaters are just arseholes (technical term) so I checked:

  There is substantial research that frustration with a slow driver in a fast lane is a significant factor in aggressive tailgating (as a way to express anger, control, or impatience) to get others to change lanes.

There's a balance between selfish lane-hoggers and selfishly impolite/dangerous tailgaters.

But perhaps research doesn't measure arseholeness?!

For selfish reasons I usually let dangerous tailgaters pass me: I want to avoid the bad outcomes from pissed off aggressive drivers.

If I'm stuck behind someone slow, I usually politely wait or politely flash lights or politely tap horn. I think Tailgating is personally dangerous as a way to signal my displeasure and I value my life highly. Polite drivers generally let one pass, and impolite drivers do whatever the fuck they want.

Regardless, it would be interesting to see stats on how risky tailgating actually is (unfortunately stats are sure to be biased by correlation versus causation).
