I do it often enough. I likewise do it on roads I'm familiar with, but I think it's almost a natural reaction for me to do it now. I don't follow as closely if I know the road is windy/bumpy, but I also don't do it unless the vehicle is large size or bigger so that I don't have to worry about the difference between its stopping speed and mine.

Anyone can do it, just think safety while you're doing it. I also ride the left hand corner as closely as possible so I can aim for the shoulder in a bailout situation. (riding on the left side of the road in Japan).
