I did take some time, but I didn’t easily find the video.
Assuming it was random, as you say, it still sounds like an unusual road rage case, which—in my observational experience—is uniquely aimed at the driver.
In a small number of cases, yes, maybe the rage wouldn’t be directed at only the driver if a passenger might have been pointing a weapon or screaming obscenities.
I didn't mean the shooting incident was random, I meant he was just randomly shooting inside the car at anyone, thus the multiple injuries.
