I filter a handfull of times in the summer at lights with a gridlock of cars. Last time I did it I got honked at and yelled at...shortly after I noticed I was coming up on a police van so I pulled into a gap and got back in line. The cop didn't even notice me pull in. Its good for a quick rush, keeps things interesting.
