(Andrea Bernstein, Transportation Nation) (Updated) New York yesterday changed its zoning regulations to clarify that yes, car-share cars can park in private garages. But Dr. Rachel Weinberger, a parking expert at the University of Pennsylvania, says, despite the city's glowing words about car-share, this plan might not really encourage people to give up their cars and use car share instead. Weinberger's reasoning is this: cities like Toronto and Philadelphia have created incentives for developers to create car-share spots, by allowing them reductions in parking requirements (the requirement they build a certain number of spots for a certain size building.) Some developers really don't want to build extra parking, because of the cost, so allowing them to reduce the space they have to build, she says, is a real incentive to create a car-share spot.
But in New York "there's so much latent demand for parking," Weinberger points out, that there's no incentive to create car share spots over other spots. To encourage car share, she says, you can't just make ZipCars more readily available, you have to make owning a car less convenient.
NY's new resolution will reduce the number of spots for owner-car use somewhat, but not enough, she says, to be a "game-changer."
The change, she said, could "result in more driving, not less," but making it easier to pick up a car-share, but no harder to drive your own.
Note: This post was updated to reflect the fact that Weinberger didn't say the new regs wouldn't make car sharier easier, but rather said it wouldn't discourage private car ownership.
