I keep my hitch in for this purpose. Once I can't see their headlights, It's game on.
I absolutely hate how grabby my brakes are, but it makes me very happy in this situation. Maybe jousting with their bumper is wrong, but hey I got 60k in loans to pay. Lets do this hombre.
But when I get my roof rack finished, ill have 18" of bright LED light bar to turn on facing rear. Prolly more civil. Maybe ill do both? Meh
