Well, not parking per se but the requirement for ridiculous amounts of it for new developments by many cities. If all urban development, including older development, met the parking requirements the city wouldn't be a city, it would be a giant strip mall development. Misguided zoning codes combined with the demands of existing residents scared of losing their parking are to blame.
I'm not suggesting that suggesting that parking shouldn't be a consideration at all, but especially for locations with good transit access it shouldn't be a primary consideration.
