“…in movies honk their horns…”

Maybe it’s just where I live (southern US) but we have a tradition of pretending to pull our own air horns down in a passenger car/truck and then the trucker blows his horn in response.

So, I can’t answer for the push button on a steering wheel. But the horns that they blow in my area are definitely from a pull string.
