People yacking or even arguing with who they are talking to on their cell phone are the worst, they are oblivious of those around them, straddling the line, swerving side to side,I've even seen a few nearly drive off the road, LOL!!!!
Others that tick me off are the ones tailgating, wanting to do 80 to 90MPH in a 55MPH, so then knowing when cops are or aren't around (radar detector) I'll get up to about 70 or 75MPH, not fast enough for the "rager" then change lanes to let him or her go,and then they are right behind you, GRrrrr!!
I feel people should go under some psychological screening for their anger/tolerance levels before being issued a driver's license, after all it's as good as a weapon in the wrong hands, I've seen so many bad accidents, some fatal.
The drivers of many cars are dangerous to the public.
My rant

Another rant, ladies talking on their cells in public bathroom, I find it offensive when I'm using the bathroom, and a person in the stall next to mine is yacking away, and loudly too!!! It just feels weird.
Done ranting.
