On my way home from work yesterday I drove through 5 minutes of the heaviest rain I’ve ever experienced. I was on the expressway and the cars went from 65 to 15 MPH in the span of a few seconds. I think part of the problem was that the rain was coming from the side at a sharp angle. The wipers just couldn’t get the rain out of the way. It extra a dicey for me because I don’t normally drive on that stretch of road. But then the rain stopped as suddenly as it started and all the cars around me made it through ok.
