I don't know the weather conditions, etc...and I certainly would not have blown my horn...but I admit that I have considered it pretty inconsiderate when I have just spent hours washing and waxing my car and someone with badly adjusted sprayers on a clear dry day doesn't wait for a gap in traffic to spray their windshield and soaked my car and ruined hours of work. Clearly if the weather is good, the dirt did not just suddenly appear and was there when the person got into the car. If it was not so bad that it needed cleaning before being in traffic....it probably wasn't too bad to wait until he would not ruin someone elses detailing. I am sorta suprised that Porsche drivers would consider that good form.
