What is your biggest pet-peeve when driving?

Here in my country, im very much irritated with motorcycle drivers who just cut in your lane without any respect or care about you. They just make their way to passed you and suddenly cut in your lane with high speed.

mine in people honking at you when you can't go because you have to wait for the other cars

My biggest Pet Peeve when I am driving is my hubby is constantly asking me if I am OK Or if he happens to be dozing off and I pull out to pass someone He immediately wakes up, jumps and make a weird noise Sucks his breathe in really hard and fast. Scares living heck out of me everytime Just plain unnerving it is Wendy

I do not like when people do not use blinkers.I know maybe people just do not want to use them.But then why doese the car have them.LOL.

People that do not know the differnece between that fast lane and the slow lane
