I don't ride more often since I got a video camera, but I do record more rides. All on the same mountain, and most are pretty boring. One time I got behind a very fast four-door sedan. I could see it go around the corner in front of me, but I couldn't catch up. I didn't have the camera on, but he finally got behind a truck he couldn't pass. It was a Porsche Panamera Turbo.
Yesterday I got behind a VW Jetta going downhill. I thought it would be boring, but he took off very quickly and I recorded it:
