The &quot;validity of the ticket&quot; is determined by rules set forth by the city and the MTA. It also establishes the grounds for invalidity of a ticket. That&#x27;s not taking advantage of the system, that&#x27;s applying the system. The right way for the MTA to put Fixed out of business is to issue valid tickets that are held to a higher degree of scrutiny, otherwise the system just rots over time, as we see here.
