"How many seconds of road do you see riding blind twisties or cresting a hill?"
Take the test on your next ride where these conditions apply ("1000 and one, 1000 and two...) Do you see four or more seconds ahead of you? Are you pretty confident you could stop (within your current count) if there was a fallen tree or vehicle blocking your lane? If not, are you comfortable riding beyond your stopping distance? I ask, because I think a lot of very experienced riders do just that - and many of them have lots more years and miles under their belt than I.
Most posts have been about following distance. Important topic and several great posts on it. Just not the question I asked. I think the experienced and thoughful riders on this forum have more to say about the question in the first sentence in this post. It was also not something that came up many years ago when I took two MSF courses. I look forward to your responses.
