Yesterday, around 8 o'clock in the evening, I returned from Oldenburg on the Autobahn and we had heavy rain. I never go faster than 120 - 140 km/h in heavy rain on the Autobahn, because that is still a safe speed there with new winter tires.
So I was doing about 130 km/h on the right lane and was inching my way towards another car in front of me, which was doing 129.5 or so, until -- after at least 5 minutes -- I finally decided to pull to the left and accelerate a bit to pass him, because I don't like to drive in the wake of other cars in heavy rain.
However, the moment I set the indicator, he started accelerating. Okay, I thought, let him go, and returned to the right lane. As soon as I had done that, he slowed down again. I thought "You sucker" and against my principles accelerated to 160 km/h -- he accelerated, too, and matched my speed.
He was then forced to slow down because of a truck in front of him (I was almost at his side at that moment, so he couldn't pull out in front of me anymore) and then I passed him and the truck, switched to the right lane again and settled down to 140 km/h.
Not hard to predict what happened next: He overtook me again with 160 or so, only to pull over right in front of me, thus covering me in water from his wake and slowing down to 130 again.
Now, I'm a patient man but that was too much for me. I slammed the foot down and accelerated. This time I did not stop at 160 km/h but kept going until 190 (rain had become a bit less in the meantime). He kept up with me until 180, then fell back. Then I pulled over to the right and gave him a nice shower for a change, which immediately made him fall back even more and then he finally took an exit.
Oh, and before I forget: It was an E36 3-Series BMW 318i with summer tires on (there are no winter tires that stand out beyond the fenders). I couldn't take a look at the driver, though. Was too dark and wet. But the chances are high, that it was a youngster in his first car, probably still under the influence of his Playstation.
