A recent study showed that it is cheaper to park a car in New York’s central business districts than it is in the other global financial capitals.

But apparently parking is a seasonal business, and it gets so cheap here in the summer that parking lot owners are encouraging rail riders to drive instead. A Streetsblog tipster reports that he was walking through Penn Station last week when he was handed the following flier.

Summer may be the best time to commute by car, but as our tipster notes, it’s also the best time for ozone production. At a time when state and local governments are encouraging people to use mass transit, their efforts are being undermined by parking garage operators targeting rail riders. Oh well. There’s nothing illegal about it. I guess all you can do is shrug, store this information away for the next time people are complaining about lack of parking, and conclude, as our tipster does, "I guess there’s no parking shortage in NYC."
