I do tha tmental gear shift on our paths, too... and it reminds me that this is how so many people perceive cycling, which is why they have difficulty comprehending why we "aren't satisfied" with "perfectly good bike paths." (One fellow on our bicycling/pedestrian commission wanted to know why we wanted the speed limit not to be raised on one stretch because he couldn't understand why cyclists should have "the right to make cars slow down, so they could go as fast as they wanted." I explained that that's what complete streets were about - making roads work for *all* users, not just automobile drivers.) It's fun ... but it's not particularly efficient and at times, not safe.
Then there are some of our paths that are just a mess, but that's another story...
