That sounds like a rough commute, I sympathize. What I'm hearing is that Sydney needs to be funneling more of the toll revenue into the transit budget so that trains and buses would be a real option for you.

As a resident of Chicago, I would be in favor of congestion pricing within a few miles of the loop. The traffic congestion doesn't just affect other drivers, but those of us walking, biking, and using public transit. I would welcome a far quieter city with less road noise more priority given to multi-modal transit.

Due to Chicago's budget issues I'm not sure how to do that beyond providing direct incentives to do something besides drive.
