Why painting the bike lanes green is a big problem in L.A.

You can't be "bike-friendly and film-friendly at the same time":

That mile and a half of Spring Street turns out to be the most filmed stretch of street in town. Or rather, it was until about last November, when the green lane spoiled the shots that made Spring the perfect stand-in for Anytown, USA. It was the perfect street for car commercials, the perfect backdrop of stolid bank buildings, the perfect mix of marble columns and Art Deco spandrels, the perfect modern or 1920s downtown — until the wide green stripe appeared.
