A guy tried rolling coal on me 2x and got into a collision.

Basically the title, the other week me(19) and my bf(also 19) were cycling around town. I can’t remember if we were going anywhere in particular, or just going on a ride, but that’s irrelevant.
We were on a decently wide residential road going downhill and we seen this red truck with a dark smoky trail turning onto the same side of the street we were on. It was coming around a the turn so by the time he saw us he couldn’t really swerve to hit us with his black smoke all the way, but he slowed down, did a U-turn in front of us, and sped straight down the middle of the road to get us with the smoke.
Like I said we were going uphill and so he was going downhill thus he was going a dickish speed down a residential at this point. Sure enough, this guy runs face-first into the ass of another guy’s car who I’m sure he couldn’t see because he was too focused on being an ass to some bikers. I heard the brakes and collision, saw the guy stopped, and looked back and said “HA HA” in the loudest voice I could possibly speak. We then promptly fucked off, and continued laughing about it for like 20 minutes.
