Britney's Crazy Caravan

Want someone to blame for all the traffic in L.A.? How about Britney Spears?!

One paparazzi agency turned their camera on photogs yesterday, filming the line of Spearstrackers who followed her from Millennium Dance Studio to her home -- the pack rolling 10 vehicles deep.

At least some of them carpool.
