+1 for Chet. The horns *ARE* useful, but not always reliable. Taking evasive action IS.
Canada Dan, it is more subtle than the difference between expectation and reality.
Once upon a time, a rider owned two nearly identical motorcycles. Moto Guzzi 850 Eldorados.
One a civilian model painted in black with a Wixom Bros. fairing and white fiberglass saddlebags...
the other one an ex-police bike with white tank, HD windshield, black metal bags.
I had the civilian for about a year before I got the PD bike. Invisible on the civilian bike, I became
the object of people's attention on the cop bike. I could slow traffic on the freeway by riding along at -5mph compared to the traffic. OR I could cruise along quite briskly in the fast lane, and most folks would move over in plenty of time for me to zip right by without slowing.
THE SECRET: Folks respond to FEAR. The cop bike represents a THREAT, so it is visible.
Trucks are threats...cars, too. Motorcycles? Not so much. So you are invisible.
THEY SEE THE COPS, so it is not a problem with expectations, but fear.

P.S. Fiamm Freeway Blasters. eBay. Bent the brackets that came with them, so they fit side by side above the front fender. Relay, heavy gauge wire, and they are not only pretty loud, but they sound...sort of elegant.
Honking after the fact is worse than useless. Go home and kick something if you want to blow off steam. But sometimes honking as the problem develops lets then know you are there, and can be useful. But reading the traffic well, and anticipating trouble, and having a way out (or two)
is going to work a whole lot better than getting into a bad situation and expecting to honk your
way out.
I work as a referee at bicycle races...so the horn gets used A LOT. Warning riders about vehicles coming by, clearing spectators on closed courses, warning riders about road hazards, scolding, etc.
FIAMMs: Loud (but not deafening), a distinctive sound (the two notes together) so they know it's me, fits in the stock location (barely), etc. Total cost about $20...had the wire already. +++ +++
