Well here it is in a nutshell. My all-time, top of the list, will get you cussed out in a heartbeat pet peeve is people who do not use a turn signal when they are driving. I mean COME ON people. it does not take a whole lot to lift your left arm, and flick a little switch up or down. I just don’t get it. It’s the law and people still don’t do it. Makes me want to just yank them out of their car and scream WHAT THE $&@% ARE YOU DOING?
I know that sounds harsh, but when I am driving around with my 4yr old in the car, I want to make sure nothing happens. If you don’t use your turn signal, then that will cause an accident, someone running into you, or swerving into my lane trying to avoid hitting you. That means they will evidently get in my path, so I will get into an accident, and that may or may not hurt my son if he is with me (which is usually most of the time). If I find out that it was because of someone not using a turn signal, then someone is getting an ass-whupping.
Its the law folks, just use them
