Ken Block, owner of DC Shoes and action sports mogul is well known for his incredible skill in a rally car. He's also been known to make some incredible videos, such as his original Gymkhana piece. For this installment, Gymkhana 5, Ken decided that he wanted to take over San Francisco: and that is just what he did. He also made sure that it was captured to perfection: I can't imagine that any less than one hundred cameras were used in the making of this piece.
Just think of all of the GoPros that must have been used alone for the bullet-time segments and all of the cameras destroyed in filming (we see a couple fall off of the the car in the film). Let's also not forget about the permit acquisition to get permission to do this; that in itself must have been a job that took months to complete. I can't imagine what it would take to close down the Bay Bridge to film something like this, let alone all of the city streets and residential areas. I can't imagine too many residents would be thrilled to have a dirt bike, helicopter, and 650hp rally car revving up outside their window at 5am.
