I used to sell auto insurance and people would explain their accident and say "I saw her running the red light (or) I saw him merging in and I Blasted my Horn but they kept coming. I don't know what more I could have done to avoid the collision." They really think honking the horn allieviates their blame or responsibity. I've seen cars hit their horn way before stepping on their precious brakes. It's like hitting their brakes is an admission of guilt or like saying 'whoops I'm sorry'. Most aggressive people can't say I'm sorry, but believe people should always be saying it to them.
