Why do people not use them?! I mean indicators on cars in case you don't know what I'm talking about lol.
Today I was coming home and the car in front decided to break suddenly then move over into the next lane...if they had their indicators on I could assume they were going to slow down.
Then at the top of the slip road they still didn't indicate.
Would I have been unreasonable to start pipping my horn at them (I didn't)
