Sorry, I didn't read your posting closely enough. I still don't think that a surcharge on new automobiles is the best way to fund support for bicycle transportation. The motorists would revolt!
Actually, Congressman Earl Blumenauer of Oregon has introduced legislation in Congress that would allow employers to extend the existing Transportation Fringe Benefit to bicycle commuters as well. It would be nice if it passes. I certainly would not turn down a few bucks a month of tax except money to offset my bike commuting expenses!
To bring thing back around to the topic at the start of the thread, I am very much in favor of California's new feebate proposal, and I sincerely hope it passes. I would love for everyone to ride bicycles, but if we could at least get them to change from giant SUVs to small, fuel efficent cars, that would at least be a step in the right direction.
