140 mm rain per hour on the German highway (long version)

I drove into a thunderstorm in Germany near Koblenz: Sorry for all the mute's I had to mute my family that panicked a bit. But they kept filming :)
Some interesting parts: After 0:42 I realised Im on a bridge. So I had to keep going to drive off it. I expected maybe high winds..
After 1:02 till 2:30 it hits the highest rain rate. I had zero visibilty. Looked through the side window to park in the emergancylane. All traffic stopped behind me too.
4:00 incoming traffic that did not hit the full rain rates. Look at the leftlane.
