Although the issue is split in the commuting section. Half take your idea, half take mine, so we probably shouldn't discuss it here. Although I will say that your idea is the one adopted in the UK, with specific bike markings where bikes sit at the front of a stoplight.
I love the train horn, although it's probably dangerous. I'd imagine it's pretty easy to blow an eardrum out with that thing. (Train horns hurt my ears when they go past.) The airzound sounds pitiful in comparison hahaha.
In the situation in the OP, I probably would have just sat there until he moved, I'm generally not in a hurry.

It's not splitting lanes, it's moving to the front of a line of stopped cars. When the light changes you are able to move to the safest part of the road without having to worry about cars turning right.
Just think if you'd sat behind the car after the light turned green and that car got rear-ended (a very real possibility).
In 45 years of riding in traffic I have never once had a driver give the slightest indication of annoyance...
