I think you're thinking of http://trafficwaves.org/trafexp.html

I read it too, years ago, and also follow its recommendations. (And I ended up in the Seattle area, so I've gotten to experience the same traffic the author did...) It makes traffic less annoying for sure, even if there were 0 other benefits I'd do it. The only freeway issue that annoys me these days is people who don't keep right except to pass during non peak times.

Yes, that must have been it. I don't remember anything about the look of the page, but his tone seems very familiar.
