Tailgating pisses me off to no end, but temporarily blinding somebody, jerk or not, is still highly irresponsible and illegal. Would you still feel justified if that same person crashed from being blinded, killing theirs and/or another family in the process? Trust me, it's a lot more satisfying and safe to just gradually slow down until they either get the hint and back off or pass out of frustration. I've been known to just hang next to a semi for miles on the freeway, only speeding up for my exit, and I change lanes ridiculously slow once I finally do.
