What really irks me are people using their cellphones while driving, telemarketers, and mothers attending to their kids while driving.
It seems that when drivers put a cellphone to their ear their brains shut down in all other areas except hearing and speaking. Invariably they can be spotted fairly readily because they don't use turn signals (they don't have a free hand with which to turn it on!), they drive 10 to 15 m.p.h. below the posted speed limit in the center lane on the freeway (and often the passing lane as well), they make unexpected lane changes, and they are totally unaware that they are sitting in your car's blindspot when you are trying to change lanes, and they pace you. For some reason in my part of the US when the weather gets really hot the cellphone drivers multiply, LOL.
The do-not-call list is a godsend but I'm sure some telemarketing company will figure out some legal way to circumvent it. Maybe a bunch of people who have been hounded to pieces with calls should get a class action lawsuit against the telemarketing companies for some major millions of dollars, LOL
On the way to a doctor's appointment today I was back of a not-so-young mother who had her child's safety seat secured in the back seat of her small car. She had her right hand between the front bucket seats fooling with her child. She was traveling about 45 miles an hour behind a large dump truck. She was so distracted that she swerved left of center and caused an on-coming car to pull into the berm. It never fazed this driving mother! About a quarter mile later she swerved to the right while fiddling with the child and missed a mailbox by inches. I stayed about 10 car lengths behind her because there was no way to determine what would happen. Luckily nothing did, and she turned off on a side street. The sad part about this was if there had been an accident she, most likely, would have survived but I doubt that the child strapped in the car seat in the middle of that back seat would have been so lucky!
