This was not the first time Dean found a parking ticket on Baby. It happened in season one, the episode with Hookman. Sam and Dean were arrested by police and Dean talked their way out of jail pretending Sam was a pledge "hunting ghosts" for fraternity  initiation. Later, Dean found a ticket on his car. Maybe pretending to be Feds etc in later years kept the tickets away. This recent ticket is near home, where perhaps, they try to keep a lower profile, when it comes to the police.
