When angry, count four. When very angry, swear.
Obviously someone at the Lancaster County Sheriff's Department is doing well with their training. Here, Deputy Ryan Schmuecker counts more than four (about ten, I reckon) and manages not only not to swear but even to be polite: "You want to pull your vehicle forward so that it's not on top of mine anymore, please?"
HT to the Lincoln Journal Star, kudos to Deputy Schmuecker for his incredible composure, and best of luck to all of us who have to share the road with the idiot in the SUV.
(PS to the Journal Star: the GL series is built by Mercedes, not BMW.)
