The California Vehicle Code says that the only things that may be legally expelled from a motor vehicle being driven on the roadway are clear water and feathers from live birds--the latter obviously being a concession to the 909 contingent. So technically, wiper fluid is illegal if it leaves their vehicle--And it should be a crime when it spots the wax job you just paid fifty bucks for. What's worse though are broken sprinkler heads in the median strips spewing a fountain over the entire roadway, not only completely destroying your detail, but creating a significant hazard when you unexpectedly hit a patch of wet road.

Next time someone sprays my car with wiper fluid I'll spray their car with pages from the vehicle code book. Or maybe with the sharp, bound edge of a vehicle code book on their faces!
