I did “San Rafael to Santa Rosa” commute, from 2007 to 2016.
I also have done “San Francisco to Mill Valley” , “Berkeley to Mill Valley” , “Mill Valley to Berkeley” over the years.
From my experience, I can tell you a few things ...
1 Crossing bridge commute is something I would like to avoid.
I have had GG Bridge shutting down problem while I was doing SF - Mill Valley, I was stuck on Richmond - San Rafael bridge once because of multiple car accident. (The accident happened on the upper deck. They had to shut down the upper deck, so that ambulance and tow truck can come from Marin county side.)
When I was doing “Mill Valley to Berkeley”, the bridge was closed (from about 8PM to next morning) due to storm + high tide.
If you do the bridge commuting long enough, sooner or later, one of these things will happen.
2 The long commute WILL wear out you AND your vehicle.
Again, that depends on how long you do that commute, also depends on your vehicle set up.
When I was doing “San Rafael to Santa Rosa” commute, I was mostly commuting on my DD (’92 NA6 Miata).
I did ride my motorcycle every once in a while, but the commute was mostly on just 101, there’s no fun (on a motorcycle, to me), due to the time I was commuting, there was no traffic jam, so I did most of the commute on my NA6.
When I started this commute, I had RE01 (Potenza) on my car. They usually lasted about 12 months before I had to replace them. When RE01 was discontinued, I switched to RE11 (RE01’s successor). I still had to buy a set of new tires from Tire Rack every year.
When I started commuting, I had a set of STANCE coil-over kit. Over the years, not only they get worn out internally, but also, one night, when I went over the bump (in construction zone on 101) one of the top hat mounting bolt of the left rear shock broke off.
If you commute from North Oakland to Santa Rosa on the motorcycle, you will very quickly wear out tires and suspension internal, and possibly drive chain and sprocket, brake pads.
3 Every once in a while, I had to take the back road due to the construction.
Depending on what time in the day you are commuting, this may or may not be a problem.
