I'd be afraid if I ever got pulled over.
The only interactions I've had with police have been as a pedestrian. Once I was walking with a friend at night, nothing more, and a cop car drove by all slow like and flashed its spotlight on us. Really creepy and intimidating. The other time I was waiting for someone outside a store and I was tired so I just sat down against the building and a cop came and stood within a few feet of me told me I couldn't do that (because of some anti-homeless laws or something).
