Living in Miami, this is no surprise to me. Driving in South Florida is an experience unlike any other. Speeding motorists aren’t as much of a problem as people who don’t know how to drive. I’ve been on an expressway, doing 70 miles an hour, and someone in front of you stops dead. Why? Because they want to change lanes and they don’t know how. So they stop dead and wait until the other lane is clear and then move over. They can’t go around curves without applying the breaks. They leave 4 car gaps between cars at stop lights, causing traffic back up. They get in the left lane of an expressway and go 40 miles an hour. They slow down to 40 on an expressway because they are on the phone. Red lights mean nothing to them. Pedestrians do not have the right of way. There are 800,000 illegal drivers in Florida. If you doubt that, take a ride through the Golden Glades interchange during rush hour. It’s more exciting than the Batman ride at Great America! I might add, I think people in South Florida take the prize for rudest…. period. On the road or off. Can you tell how much I love it here? Oh, and they can’t drive boats, either. They’ll smash into other boats at a marina and when they finally get into their slip, they’ll scurry out of the marina as fast as possible in case someone just saw them playing bumper boats on the way in. But hey, it’s paradise, right?

Stressed Miami drivers speed, tailgate and cut off other drivers so frequently that the city earned the title of worst road rage in a survey released Tuesday.

AutoVantage, an automobile membership club offering travel services and roadside assistance, also listed Phoenix, New York, Los Angeles and Boston among the top five cities for rude driving.

Minneapolis, Nashville, St. Louis, Seattle and Atlanta were rated as the cities with the most courteous drivers, who were less likely to change lanes without signaling or swear at other motorists.

More than 2,000 adult drivers who regularly commute in 20 major metropolitan areas were asked to rate road rage and rude driving in telephone surveys between January and March. The survey conducted by Prince Market Research has a margin of error of plus or minus 2.2 percentage points.

Drivers owned up to some rude behavior themselves: Nearly all said they had talked on a cell phone while driving, and 64 percent acknowledged they occassionally drive too fast.
