I love the camaraderie of the roads. We motorists, us drivers, we look out for our own. Always yielding politely to each other, flirtingly flashing our lights in thanks. We need more of this. More discussion, more back and forth, more meaningful driver shorthand.
In particular I would like a designated light on Purple Danger which denotes 'Don't fucking flashingly thank me motherfucker, I let you in by accident because I was day dreaming about my death and it's not like you gave me much of a choice anyway, you undertaking, 05 Micra wielding cunt'.
More communication can only make our roads safer.
