Hell, I've even considered early on what it would be like to have a horn on the dash, and if I can upgrade it to a Stebel Nautilus horn to make an impression around blind corners on mountain roads where honking is the "in-thing" to do.
Honking on blind corners on mountain roads is not, unfortunately, the "in-thing" but a courtesy that is being forgotten in these days of hermitically sealed cars. On the mountain roads around here I always honk and I wind the window down, a little even in winter, so that I can hear. It annoys the h!"% out of me when others don't do it.
