That's an interesting thought, larry. I've only encountered a few drivers on the road that made me think 'that's probably a hypermiler' but then again it isn't always glaringly obvious (esp. since there is a spectrum of mild-moderate-extreme hypermilers).
When it fits, I throw 'hypermiling' into conversations to see if it is well received. Hey, at least it's in the
dictionary.
1%er...hmm...you're probably right. But I suspect that there are a few people who use some of the techniques without knowing the term - just out of common sense. Even some users around here have said things like: I've been coasting to red lights for years just because it makes more sense. Not sure if that counts.
