I'm not a hater, especially on the road. I used to be. In fact, I once saw a movie featuring Ken Wahl in which he tricked out a pick-up truck and went around harpooning drunk drivers. I was so taken with that idea, I wanted to do it to bad drivers. Over the years though, I've mellowed and I have now only this observation:
Bad Drivers are like birds, they come in all kinds of varieties:
The Nimrod- gets in the wrong lane and then cuts over without looking, or sits at the light that just turned green for a minute because they're lost in their cell phone conversation.
The Peckerwood- drives 55 in a 65 until you try to pass them, then they speed up to 75. If you give up, they slow down. Peckerwoods do this without knowing they do it. There is another species that does this intentionally and maliciously, and I believe they are the Rednecked Assbag.
The Dipshit- This species is known for a plethora of bad moves, most notably for creeping into a backed up intersection. Though they do this during a green light, it's almost assured that the back-up will cause them to still be in the middle of the intersection when their light changes, further backing up the intersection. The amazing thing about this species is that they seem to do this same maneuver again and again.
The Poser- this species drives a pick-up truck though they almost never actually haul anything with it. The rear window will be festooned with racing stickers, either of performance parts that they would like to have on their truck, or of NASCAR racers they like. (There is also some variety in the plumage depending on the region- if for example, you spot a Pick-up Poser with a WEBN sticker on their back window, be prepared to give them a wide berth as there could follow any number of seriously assinine driving maneuvers). The Poser's driving is among the worst known to man, featuring unnanounced lane shifts, random acceleration and slowing, wandering from lane to lane and other strange acts of driving incompetence, most of which is marked by the driver assuming the "cell phone to my ear" position. It is easy to confuse the Poser with other species of men who drive pick-ups; the general rule of thumb is that the cleaner the truck bed is, the bigger the Poser.
The Serious Ass*ole- Runs red lights and stop signs, often at a high rate of speed, because they are in such a hurry to get to McDonald's or whatever dumbass place they're headed for. As a motorcyclist, I hate this species and encourage you to also.
The Flatout Nutjob- this is a species I've experienced to be especially native to New England, though it may be native to all rural areas. These drivers get paranoid on the highway if you approach them too fast from behind and will actually slam on their brakes to teach you a lesson about going too fast or getting too close. Sadly, their tendency to drive in the left hand lane of the highway at or just slightly above the speed limit makes them much like little psychotic bombs just waiting for you to come up behind them and set thyem off. In some rare cases, Flatout Nutjobs get so worked up they follow you home or spend many highway miles harassing you to ensure that you've learned your lesson.
The Celler- we've all seen cell phone users do some dumb crap on the roads, so all I have to say about this one is that I actually had someone on a cellphone walk into me at the mall the other day.
Now, fair readers, what species did I miss? Please add your observations to the comments!
