What driving habits of the other drivers annoys or scares you the most?

People who swerve, usually they are drunk. I really don't like people who see an emergency vehicle approaching from the other direction with a clear road and they slow down, get just halfway off the road and stop. I used to be on an ambulance and we used to cringe when people did that, just asking for a collision from behind. The only time one needs to get out of the way is when there is no way for the ambulance to get past'.

When people drink and drive ...also people that let their dogs jump from the front to the back seat and people that hold their dog or cat on their lap as they drive.

its not a driving habbit but im always super scared when im stopped at a red light behind a vehicle that's bigger then mine. one time i was stopped and for some reason the truck infront of me started backing up and totally smashed and totaled my car. he said he was backing up because he thought he was in the crosswalk and he didnt know there was a car behind him. luckily i didnt get hurt but he wrecked a car i loved! lol

When ppl don't know the difference between playing bumper cars and being in a real car on a road.

I hate it when they don't signal when they want to turn left or right.

I hate it when they horn at you for no reasons.

I hate it when they cut in front of me.

"OTHER drivers"? i'm not a driver, but i hate it when people drive and text at the same time

I don't drive but speeding scares me.
