Several years ago I was driving my 7.3 Diesel on a back road in rural north Florida. I got behind a young woman in a Toyota Camry who was going about 15 miles per hour under the posted limit. I pulled out to pass her and she gunned it and pulled away from me, so I pulled back in behind her. She immediately slowed back down again. Every time I pulled out to pass she gunned it and I couldn't get by her. When I pulled back in she would slow down again. My truck didn't have the juice to pass a stinking Toyota. I followed her for almost an hour before I caught her by surprise and got a head of steam up and got by her. Very frustrating.
