I've been driving for many years. Each area of the country has it's own driving style, but there are "trends" and generalities regarding driving styles that are nationwide.
We've all seen the teen and twenty-something drivers' tendency to have the seatback angled so far back, that the B-pillar obscures the driver's side vision, (and they can barely see over the dash). I call this "Hip Hop Driving" posture. It's a driving style that crosses all races and cultures at this point in time, but seems to be a "youth" driving style, only. (Luckily, it's now starting to fade as a fad).
Then you have a whole genre of driver that uses cellphones in traffic, and becomes a completely distracted asshole driver, without even realizing it. There are "leaners" that hold the phone to their ear, and lean their head in the direction of the phone, and actually spill into the lane next to them (that they are leaning toward). Then there are the Bluetooth users, who think they are "driving safely," but are so distracted by their conversation, that they are driving 15 MPH slower than the traffic around them. And then there are the worst of the bunch...people texting while driving. This started as a 16 to 26 year-old driver phenomenon, but I now see it being used across most generations. "Aren't I cool; I'm a 40 year old Soccer Mom, and I'm texting back to my daughter while driving on I-35, during rush hour."
Sometimes there are very apparent signs that you should avoid a driver. You can spot the clueless or uncourteous driver from afar, very much like seeing a porcupine with it's quills out in the wild. Of course, I'm talking about the "too many magnetic ribbons driver," and "too many bumper stickers driver."
You know, one magnetic ribbon to show that you support the troops (or are patriot) is totally cool, but when you have an entire platoon of the damn things stuck to the back of your car; well...it usually means you are trying to over-compensate for something, or your are trying to shove your particular message down the public's throat. (The same holds true for having too many bumper stickers).
In fact, I think that the number of ribbons or bumper stickers is directly proportional to how big of an asshole driver you probably are. Too generalize further, (at least with the mag-ribbon phenomenon), these things are usually stuck to the backs of full-sized Buicks, Ford Taurus', Mini-vans, and American-brand SUVs and Pickup trucks. So, if you see a tope-colored Taurus in front of you with 6 mag-ribbons on the trunk, beware: he or she is about to change lanes (with no notice) and slow down or stop in front of you, for no particular reason.
I'm not a psychologist, so I'm not even going to hazard to guess why there appears to be a relationship with the multi-ribbon and sticker set and their anti-social driving habits, but I'd love to see a study done.
Peace-out, and drive carefully, please!
