ok i doubt anyone else shares this particular neuroticism but... say we're driving down the highway and someone else is driving and i'm in the back seat. Often i'll click my teeth (just kinda bite down or something lightly ) for every one line and try to do it for each white line and then stop eventually when i realizei t would be impossible to do it for all the lines.

I'll do this (but with me I'm generally shooting an imaginary line in my mind through the gap) between lane line markings, between open spaces where a row of cars line up, between guardrail posts, etc.

Replace clicking the teeth with flexing the hamstring in the leg "on that side" (so as to tighten the tendons behind the knee) or both of them if a line defined by the placement of my knees travels through said gap.
