As if American roads weren't dangerous enough already, you'll now have to keep an eye out for Twitter users.
That's because the service is checked more often while driving than other sites, such as Facebook, according to a recent survey by research firm Crowd Science.
With its concentration of techies and drivers, the news doesn't bode well for Twitter's hometown of San Francisco, which already leads the nation in pedestrian fatalities from car accidents.
So please, don't tweet and drive.
You might run over a Twitter engineer, and where would that leave Twitter addicts?
