There's issues, sure. Generally though, we've heard reports from many places of long-term 5% fare evasion rates. System-wide the number reported here is 5.4%, and only 3.7% on the subway and 5.1% on the bus.What an epic clusterfuck. It's almost hilarious if it wasn't our money on the line.
Yes, 15.2% on the streetcar is a problem. But everyone seems to be focusing on the Child Presto issue. However the report notes that the issue was Child Presto being abused on buses and subways. Presumably fare inspectors are enough to discourage this as much on streetcars.
This also means that just focusing on Child Prestocard isn't going to deal with the streetcar issues.
Clearly the TTC has been understating or not even realizing the issue. But 5% system-wide hardly seems in clusterfuck territory. More so that TTC is only doing as well as many other systems.
Standing in a New York subway station, and watching all the people enter the crash gates there without paying, I'd have a hard time thinking that they only have 3.7% - it seems much worse there in my anecdotal observations.
