Local designer Brian Singer is on a mission to embarrass the shameful, dangerous behavior of Bay Area drivers. Singer, who commutes down Highway 101 between San Francisco and the peninsula on a daily basis, has been collecting photos of drivers texting while in traffic (or "TWIT spotting," as he calls it) and putting them up on billboards around the city.

Singer started the project after noticing a terrible amount of drivers on 101 tapping away on their phones. "I've been blown away by the number of people texting while in traffic, on the freeway," singer told Gizmodo. "For every nose picker, there's 20 texters. Unofficial estimation by me."

As a passenger on his daily commute, Singer started photographing all the ones he spotted and posting them to twitspotting.com. (The blog is now also taking users submissions (just don't be driving when you shoot them.) It's Singer's goal, he says, to make people think twice about picking up their phones while behind the wheel.

After trying to get funding for the billboards from distracted driving associations, Brian ended up paying out of pocket for the billboard-sized versions of the photos. The ads, which carry no copy and feature nothing but a photo of a driver engaged in illegal activity, can currently be seen over Broadway on the edge of North Beach/Financial District, alongside Highway 101 and on Mission Street, among other places.

Singer can now list himself alongside Stanley Roberts in the great history of San Francisco do-gooders.
