It sure is nice to know the power is there when you want it.
Ironically, a few weeks ago I was driving to work on I-95 between Bridgeport, CT and Westport and got passed by an Insight. I was driving with the cruise on at about 67-68 and the Insight pulled alongside, the driver looked over and gave a little nod and then accelerated away

.
Of course, I could have easily kept pace, I just didn't want to blow my mpg for that trip.
