For the person to apologize .For the person to revoke their license .For the person to pull over and explain why they did that .For the person to realize they messed up .
What may be the reason for laying on the horn ?
I get to the merge point , and he goes flying right through his stop sign . I have to slam on my brakes , I lay on the horn ... at least he bothered to realize " Oh , shit , I just fucked up , did n't I ? " And pulled over for a second to make sure he did n't make me go flying off the road or anything . But only for a second , then he starts up again , waves his hand out the window in an attempt to say ' sorry , ' and turns up into the development .
