Hello. I would like to tell you a little experience and maybe you can solve the riddle. I was shopping today, about 30 km of highway from my place of residence. The road is rather narrow and very curvy with many villages in between. After a few kilometers on the drive, a car snake starts in front of me. At a very elongated curve I could see a tractor in front. The car snake behind the tractor was certainly 300 meters long. Suddenly dive into my m rear-view mirror a thick Ami pickup, I would say as a layman a Ford so 10 years old. The distance was absolutely impossible to see on the kilometers because on one side forest, some hills before the next turn etc.. He pulls by me with full throttle begins to overtake the snake. I thought he wants to take his life and already thought if I still have the small fire extinguisher in the trunk, maybe there is still something to save. But he managed, though as I said every 100 meters behind the next turn could have arrived a 40-ton. Now I wonder why he overtook me? 1) Magnificent and incredible luck (probably rather improbable) 2) .. good question .. To make it clear again: Absolutely impossible to see the driving track. 2 strict curves he has crossed. Can you clarify the puzzle? Are there radar cars in America that have everything within a radius of 5 km in view?
