"Sure, that's been the mentality, but it hasn't worked yet."

Then I would say things haven't, yet, gotten bad enough. When that happens you'll likely see some changes in behavior. If I lived in say West Eugene and worked downtown, I'd be figuring out how to best access the Fern Ridge Bike Path ( Amazon Creek ) for as much of the year as the weather permits. It's a pleasant enough ride, and you get the benefit of the exercise. Or I'd be working out ride sharing, park n ride, telecommuting is available, shift adjustment, anything.... Unfortunately, most people are loathe to think outside the box.
