If Yove Been Riding For Any Length Of Time You'll No Doubt Recognize Some Of These People

Aunt Myrtle
Drives a K-car, or a cheap Pontiac, or similar economy cage.
Aunt Myrtle, late 50's to early 60's, will stop and look at intersections, often sitting there for a long time even when she could have merged in. Once she has decided that she's waited long enough, she will pull right out into traffic, regardless of what's coming. Can be persuaded by a loud horn, occasionally, but don't count on it. Aunt Myrtle gets very mad when forced to stop for a motorcycle. She respects only trucks and buses.
Careful if you're behind Aunt Myrtle entering a divided highway. Her idea of merging is to drive to end of the on-ramp and stop there. If you're coming down that highway, Aunt Myrtle will stop, look at you, and then pull out in front of you without further ado.

Aunt Millicent
Drives a large Cadillac or Lincoln, usually grey or putty colored. She does not always stop at intersections, regardless of red lights or stop signs. Usually she prefers to roll through at her regular highway speed, which is between 15 and 27 miles per hour.
Once Aunt Millicent has made up her mind to go, there is *nothing* on God's green Earth to persuade her otherwise. Watch out for her, even the trumpets of Jericho won't stop her. When confronted by oncoming traffic while she is entering the highway, she will look the other way, hunch her shoulders, and keep going.
Drivers in England use the left side of the road. In America, we use the right side. Aunt Millicent prefers the middle, for greater safety. On I-40, Aunt Millicent observes the speed limit carefully and stays just below 40, which in her opinion is what those red-and-blue signs are showing. On I-20, she breaks the law and speeds along at about 35 mph.

Uncle Edwin
Uncle Edwin (late 50'ish) drives a nondescript domestic car, preferably a Chevy Caprice.
He likes his brakes. Police car parked on the other side of the road? Uncle Edwin brakes, regardless of the fact that he was only going 36 in a 45 mph zone. Traffic pulling in about 1/4 mile up the road? Uncle Edwin hits the brakes. Going uphill? Uncle Edwin hits the brakes as much as possible.
Uncle Edwin also likes to make wide, sweeping turns. If you see him pulling into the right hand lane, be prepared for him to make a left turn out of that lane.
Likewise, Uncle Edwin does not like center turn lanes on city highways. He feels that it is safer to come to a stop in the driving lane, and then cut across all three to make his turn.

Flip
Flip is in his late teens and drives a would-be sports car, or sometimes a real one. His mustache consists of 11 hairs, which bothers him a lot, so he has to drive like a maniac to prove to everyone that he is a real man.
In Andrews, North Carolina, the Cherohala group watched Flip spin his wheels proudly on a wet road. Flip likes to tailgate bikers to show them that he, too, is the sporty type. Don't get into any duels with him, because he is not as competent as he thinks. At the very least, he'll flip
you a bird.

Tipsy
Tipsy is Flip's female equivalent and drives a red compact car which daddy bought for her as a graduation present. She pretty much drives like Flip. Being a college student (and very proud of the fact), she can be seen motoring toward the campus on exam days with a book propped on the steering wheel. Stay away from her, driving and Sociology 101 don't mix.

Soccer Mom
An attractive female in her mid-thirties, Soccer Mom drives a Chrysler Caravan or a Ford Aerostar. She will do all of the things mentioned above, except for flipping the finger. Soccer Mom is the one most likely to be talking into her cell phone while driving. Quite often, she's holding the phone with one hand and disciplining her kid in the back seat with the other. The road gets only scant attention, so Soccer Mom will pull out into traffic, tailgate motorcyclists, run red lights, turn without warning, or try to share your lane. She doesn't mean it, it's just that she is completely oblivious to the world around her. All of us have had some close brushes with her in traffic.
When startled by the motorcycle's horn, Soccer Mom looks out her window indignantly, wondering why The Government allows those nasty people to ride those big, dangerous machines. She resolves to write to her congresswoman about that.
