My brother in law got a parking ticket with a rental car along venice beach. They sent him a notice, he ignored it. Then about 6 months later he got a certified letter from the court that say pay or show up. He ignored that. Then he got a notice from his state's DMV that he had an outstanding ticket in CA and his license would be suspended if he didn't take care of it. Since there was no way I was driving all the way down there to handle it for him, he paid it and it went away.
