Driving down I77 southbound with my wife. It's dark and raining and we're going about 75-80mph in the Miata. I look in the rear-view in time to see 2 lights just about wreck into me, then swerve at the last minute to go around me. It's a minivan going I'd say about 110-120mph. About 1/4 mile up we see it almost sideswipe a car then takes up 3 lanes trying to straighten out. We lose sight of him for about 30 seconds and see brake lights. The guy ran smack dab into the end of a highway divider. I pass by him and see him crawling out of what's left of the minivan. I told him he was driving like a fucking idiot, called the cops and left. I wasnt about to put our safety at risk to wait around for the cops. I did give them an earful about what this stupid fuck was doing. Another witness was gonna stay and wait for the cops, hope he doesnt try to sugar coat any of this guy's bullshit driving. If he would have hit me, I'd be on the way to jail for smashing his face in with a crowbar, then running over the corpse repeatedly.
