First, why would you subscribe so heavily to an idea that several very experienced riders insist is a bad, bad course of action? Every time I've come to the CSC looking for good advice, I've found it. (Dana's insistence on going stunting after downing 15 jello shots not-withstanding ) Listen to these guys.
Second, if you really insist on travelling this path, drop California out of all your arguments. Just because it supposedly works there doesn't mean it can here, and I think you hurt your case every time you mention the "C" word.
Alot of native coloradoans actually have a deep seated animosity towards everything Californian or Texan. We blame them for moving into our state in droves during the nineties, congesting the roads, ballooning the brown cloud over the city and driving the cost of everything up.
Back in the seventies, Colorado had a chance to compete to host the winter Olympics here. A public referendum failed to pass because we wanted to avoid the influx of people and problems into our state. Years later, mayor Pena and Gov Romer finally got enough of a kickback from the tech industry that they sold us out, made deals to attract Californian and Texan tech companies to relocate here, built an airport we didn't need (and voted against), and since then, we've watched our cost of living skyrocket while our standard of living has, on average, gotten worse.
Oh and... Before all these pricks moved into our state, there was no need for lane splitting. A bad traffic jam was one that slowed you down for 10-15 minutes. Now that's just an average commute into the city on any weekday morning.
You want ease congestion and make the road safer? Make the D.L. requirements/testing harder.
