I can, but it is frightening. I had to drive in to work on my own this morning. I usually ride in a carpool with a guy who refuses to go slower than 75, usually speeds along at 80-85. When I drove on my own in the past, I usually went 70-80. So with gas at 2.83 and remembering the "drive 55" campaign of old, I decided to see if I could keep my little hatchback between 55 and 60 mph and see if that made as big a difference in mileage as the experts say it does. So there I am driving in the far right lane of a major 6 lane highway (3 lanes each way) averaging about 58mph. Talk about angry drivers. It was bad enough watching the innumerable large SUVs, big pickups and sedans flying by me as if I were standing still, but the ones going 70 in the slow lane came up behind me furious that I was in their way. I lost count of the number of big SUVs and large pickups that would come within a few feet of my bumper before passing me and nearly clipping my back end. The entire trip I passed no one. There was one car matching my speed - a Prius that followed me for a while before exiting. 58 feels like a crawl if everyone else is doing 75+. On the plus side - I made it to work at the same time as I do when I'm traveling 80. The backups and bottlenecks on the interstate and beltway are the great equalizer. Also, judging by where the needle is on my gas guage, the difference in gas used was tremendous. I guess I'll tighten my seatbelt and drive 55 on the way home as well.
