When you travel from San Anselmo and San Rafael toward the downtown area of San Rafael, there is a motorcycle cop who often sits in the Center Median right after the McDonalds (across the median). Some times it is so lucrative two of them sit there. It is zoned 35 mph, but because it is 3 solid lanes of unobstructed travel, with no ingress or egress and an 8 foot brick wall on the right hand side, it is actually safe to drive 45-50mph. The speed test designed by San Rafael City to set the speed at 35 was done improperly (illegally) and did not take these features and many more into account.
