Rigger,
Have you gone over "to The Dark Side" with this poll?
I expect us Insight drivers to "win" since it is the most "Anti-Hummer" vehicle out there.
I had a bad job once where some of of us were killing ourselfs while some were not putting an effort at all. Are the overachievers "smug"or frustrated? That could be a matter of opinion. The non-acheviers simply did not care, were stupid, or both.
Back to the highway - there are numerous examples of drivers that obviously are not paying attention to driving for safety or decent fuel economy (read: not to the exteme of hypermiling). It does not take that much effort to drive safely or to get decent FE. I'll suggest the really smug drivers are the ones I've pointed out that seem to think they can drive in a trance or on a rampage.
