Speaking of Prius drivers....we have those signs in PA that state "No Idle Diesels Over 5 ton GVW". Anyway, one day at our local Rite Aid Pharmacy, I left the Sprinter running in the parking lot while I ran in to pick up a prescription. My wife and my mother were sitting in the van with the AC's running.
When I came out, this woman starts screaming at me "Can't you read dumb ***?" "The law says you can't idle a diesel". I responded "I may not be able to read, but can you do math? How many pounds are in 5 tons? Now come here and look at this tag. What does that say?" She responded "8550". So I aked her "how many tons is that" She replied "Not quite 4 1/2. But it's the point" and stormed back toward her car, which happened to be a Prius.
As she was driving away, she gave me the finger. I just happened to notice that she wasn't wearing her seat belt. As luck would have it, one of the troopers I work with regularly just happened to notice the same thing just a couple of miles down the road. I waved politely as we drove by.
