87.My boss is forever teasing me for driving slow. I usually drive 55-70, and he is amused. He has a lead foot. So I went fast and took a pic of the dash! He said I had no proof it was really my car. Hybrid had no difficulty getting up that high. Faster I ever drove was on 1-95, Summer of 1986, driving home late at night from work with my older brother. We worked at the same McDonald's, and shared a 1973 Chevy Impala with our other brother. One night we decided to see what that big old hunk of Detroit steel could really do. It could do quite a lot as I recall. Something around 120. How we were not killed or pulled over I have no idea.
