From US News & World Report:
The worst drivers in America live in New York. Of course, you knew that. You've been in the Holland Tunnel. But now, we have proof.
GMAC Insurance has released the results of its National Drivers Test for 2009. The test, which measures basic knowledge of driving laws, was given to more than 5,000 drivers from all 50 states and the District of Columbia -- and New Yorkers finished last. Last year's loser, New Jersey, improved its score just enough to leap over New York. Hawaii, California and Georgia rounded out the bottom five.
Evidently, Idaho and Wisconsin have the best drivers. My home state of Illinois came in 29th.
