When I visited America recently (LA, San Francisco and Las Vegas), I noticed loads of people talking on cellphones while they were driving, far more than I see on British roads. I found it rather disgusting, and I can't believe they all get away with it, if I was a cop in any one of those cities I'd be pulling loads of people over. If you must talk on the phone while you're driving (I wonder how many people are making important calls while driving or are just being assholes making social chat calls), at least get hands-free kit (I'm not sure how they cost) so you can have both hands on the wheel while you're driving. Americans also seem to have a habit of driving too close behind each other.
