About as many times, but the key thing is that the horn is only useful if I'm static since otherwise it's faster for me to evade than honk. I estimate ~0.5 s to 1 s net delay to action if I were to honk, with 0.5 s to 1 s delay in action from other person if they're fast. At a 2 s delay, unless I'm not moving, evasion + braking seems superior. And evasion is made harder while honking. I've had many times where people run red lights in front of me (I live in SF) but I've never honked. It's frequently too late to do anything so I just brake.

The point I was making was that something doesn’t need to be used often for it to be important and for you to want it to be reliable.

Also, the horn is a signal. It allows you to evade and alert other users that something needs their attention. Maybe they need to avoid you while you avoid something else.
