Few weeks ago I was on a 2-lane road without a lot of passing opportunities. Three cars in front of me going 52 mph in a 55 zone, and not enough room to pull in between them and pick them off one at a time. Finally found an open stretch where I could comfortably take all 3 at the same time. Pulled out and put it to the floor. Didn't look at the speedo until I was passing the last car and was just topping 110 mph. Really hadn't planned to be going that fast.
I'm sure they about crapped in their minvan as I went by.
