Actually, it was inspired by
this guy that manages to pull off some serious asshole driver moves by squeezing between cars. Awesome soundtrack, though.
Speeding up the footage by 4x makes the maneuvers look aggressive, but all the driving I did was normal and calm.
If anyone else can do this for your city, I'd love to see! (I
really wish I had done this with Atlanta!) Record your commute, drive across town, whatever. You don't really need any special camera mount, either -- I simply jammed the camera into the hole in the center of the seat's headrest. A beanbag on the dash might work just fine, too.
