This is terrible, no one should be shooting at another vehicle ever. Hope the satisfaction he gained from sending a rude gesture to another driver was worth his partner's death.
My gf gestures at other drivers while I’m driving. I’m just, please, stop that. I’m not upset enough to gesture or yell at people and I sure don’t need her to do it for me, and some people are genuinely insane and also very dumb. It’s not worth it.
