Sounding the horn

I watched a car slow its pace. It meandered with some uncertainty. The brake lights illuminated near every cross street.

A frustrated driver who was closely following the lead car leaned into his horn. Beeeeeeeep.

Some considerations:

Does this kind of honking ever work? Does it ever help someone to find their way? Does it ever bring clarity to the situation? Does mere honking on these occasions effect positive change?

(If you’re reading this as a metaphor, that’s a fine thing to do.)
