I attended a symposium in DC last week and I drove. Coming home, after getting clear of the rush hour traffic, I set the cruise control to 65 (speed limit on I-95 in most places) and had the most harrowing trip I ever had. There was no one in any lane going that slow.
It brought to mind something the teacher said when I took my first driver ed class decades ago, to reduce the cost of my car insurance. He said go with the flow, it's less dangerous. I was determined to go the speed limit, but I felt like an endangered species doing it. I'm not kidding, it was nerve wracking. They were like shooting stars whooshing by. I should add that no other teacher had the guts to speak the truth on this. Slow pokes endanger themselves and everyone else, even if the slow pokes are going the speed limit.
