This is just to satisfy my curiosity: a little survey. Does anyone else have the following issue?
I have an issue with driving fast on the highway. It's a combination of substantial lack of patience and boredom. My father had the same issue, so I believe this is a genetic disposition. (However, I note that a lot of other drivers also seem to cruise at fast speeds these days.) On familiar interstates where there is a clear line sight and no speed traps, I often travel at about 90 MPH. In unfamiliar areas, I travel 14 MPH over the speed limit. On my last road trip, I was traveling at 90 to 95 MPH frequently to cover more ground in less time.
Regarding my last trip: On I-20 in South Carolina, I was traveling very fast as 90 to 95 MPH on open highway. On I-40 in Tennessee I was traveling about 90 MPH once I got out of the mountains. On I-26 in South Carolina, I was traveling at about 85 MPH largely inhibited by traffic.
I take some pride in knowing when it is safe to speed and where the speed traps will be using only my eyes. My speed is rarely constant local to my area of the country because of the rolling hills. Cresting a hill is more dangerous so I slow down at those points. When I feel patient, I often set cruise control at the highest speed that is safe by my definition. Just so that folks do not assume that I am a total jerk, I respect construction zones, keep lots of space between my car and the next, and slow down to pass so that the speed differential is not dangerous for the slower moving vehicles. At higher speeds, I become like a hawk, extremely vigilant of dangers.
