I park my car on the street I live on in San Mateo. I do not have a driveway and have no other place to park. I went on vacation and they towed my car for being parked in the same spot for over 72 hours. No signs posted anywhere about this, it's just some ordinance we're supposed to know about. Cost me $820 to get my car back. They could easily post this information on the street signs, but then they wouldn't get all that nice revenue. Be careful not to break the obscure laws they purposefully keep hidden from you. They will make you pay for it if you do.
