I had another encounter with a moron.
That was a Challenger Hellcat. The dude probably saw me passing traffic and I ended up behind him on the highway. He started passing people on solid yellow lanes, in curves where we could clearly see cars coming head-on in the other way. 2 cars had to get off the highway otherwise they'd have collided with the dude. It all happened in roughly a minute, I just let him go. Hell, I like speed, but no need to kill the kindergarden teacher (or whoever that was) coming back from work in her pretty little flashy green car.
