My newest rant is those who remain blissfully unaware when an Ambulance/Rescue Unit or Fire Truck is coming up behind them. Even without all the lights, sirens and horns, people should see them coming. Lately, I've seen a number of clueless idiots - one just the other day who changed lanes into the fast lane in front of a hauling ass fire truck. If not for the quick response of that fire truck driver, that Subie would have been squashed!
