What? You honk your horn every time you enter an intersection where a driver is present and could cross your path? Because if they're already crossing your path then honking your horn is the last thing you should be concerned with.
Then maybe you should explain what you're actually doing because I'm an urban rider, my friends are urban riders, and the general consensus in our local motorcycling community is the horn is useless. Because like I said, if the driver isn't crossing your path then there's no reason to sound the alarm and if they're already entering/crossing your path then you'd better be engaged in crash avoidance. It's not clear when you're using your horn.
