The only time I ever got that angry was when a car tried to force me into oncoming traffic.
Coming up to some traffic lights with two lanes of traffic on both sides of the road. I was in the right lane going straight ahead. Car on left was in the lane to turn left.
As the traffic moved off he thought he could get in front of me from the left lane. He didn't and just kept moving over to the right. The only choice I had was to stop on the other side of the white line, or be knocked off.
I caught up to him at the next roundabout. Pulled alongside him, and called him a few choice words. Saying you could have killed me. I was really angry. But the terrified look on his face. And the fact he was trying to climb into the passenger seat calmed me down.
Not really my proudest moment.
