But I've heard the same comments enough times to make me wonder how American drivers are so bad.Lack of testing, for starters. There was a time, going on 40 years ago, that someone observed my driving and decided whether I was safe to release upon the roads. Since then, I've taken a knowledge ("written", though it's computerized now) now and then. The last time was 16 years ago when I moved to WA. They check your vision at renewal by testing your ability to check a box that says "yeah, my eyes are fine".
Add to that a lack of enforcement. As long as you don't exceed the speed limit or have booze on your breath at a checkpoint, you might go your whole life having never been pulled over no matter how much texting you do.
Here in Seattle, which I maintain has the worst drivers in the country, my current working theory of the cause of horrific driving incompetence is self-absorption that seems to be particularly rampant here. Why else would I get regularly flipped off when the light turns green and I honk at Ms. Tweets McFacebook to put her phone down and drive?
