What is your biggest pet peeve regarding other drivers?

I hate left lane lurkers on 4 lane highways. They cruise in the left lane, holding up traffic. The left lane is for passing slower motorists.

Even with all the laws, publicity, and waarnings the distracted driver is the worst.

I have to agree with the ancient one.

Distracted drivers are the worst. From eating to applying make-up to in vehicle arguments.

The worst is drunk dtiving.

Equally bad is cell phones. It has been proven drivers are also as distracted when their passengers are using the phone.

Come on !!  Who are they trying to fool ? When a driver is looking down and smiling at their crotch ...you just know they are using their phones.

All of the above plus the ones that go from lane to lane.

One of the biggest for me is when people litter or throw cigarette butts out the window. I will tailgate you with my brights on and horn blaring until you pull over and think about what you've done.  As soon as I get a dashcam I'll be posting videos. So if you're one of those people, you might just be a guest star on trashy traffic trashers. Just made that up XD

I dislike those drivers who seem to think they own the road. Everyone should know that I own it!

The ones who obviously have no clear destination in mind and yet are constantly acting as if they have already arrived.

I hate it when someone does something dumb and then acts like it is YOUR fault! When I get flipped the bird I just tell them "thank you. I know I am number one!" Lol!
