Airboner,
Before you get any more road rage.... think about where your hand goes the next time you reach for the horn... and plant it WHERE you know your horn button is now that you're found it. Calm down, theres no reason to go all apes because you hit the BT button when you wanted to honk your frenzy out on the horn!
Cheer up, all is not lost, airboner.
Sanosuke!
