I have driven on CA 91 and noticed that toll option. There was almost no traffic congestion on the free side, so I'm glad I didn't squander the $11. There were a few people driving on the toll side (this was on a Saturday I think).

I would prefer that tolls be charged on the entire highway, not just half of it. I don't like the idea of segregating traffic on a public road based on ability to pay.

I'm fine with paying tolls to drive on a highway. Recently I chose to drive on I-44 (tolls) through Oklahoma rather than taking US 67 just to avoid traffic lights in all the little towns along the way. It was $7.00 one way from Oklahoma City to Missouri, a good distance and for $7, a fair deal IMHO.
