Rain means one thing: it takes you longer to come to a full stop. That is all it means. I navigate puddles of 30 cms depth on my daily commute, and I have slid across them on the underside of my car. It is not a problem, unless you start turning the wheel, braking and panicking,. You just roll over them. If you aquaplane, you take your foot off the gas and keep the wheel steady. You don't brake. After navigating a really deep puddle, you hit your brakes fully at least twice. To dry them off. Whenever I am driving I turn into a lean, mean calculating machine, looking far ahead, assesing distances, my speed, other people's speeds, overtaking distance, car power, road conditions, braking distance, deer danger, etc. And to me most danger is coming from other cars. Not rain, not snow or ice. So once I hit the road, unless I feel you are paying attention to your driving - which includes indicating, you are a hazard.
