If you use one of these on a cyclist in a large part of the U.S., your ass is grass.
If said cyclist crashes (which he will) and is injured (which he will be), you're 100% liable for all damages. And there are quite a few personal injury lawyers who have been trying this exact same case again and again for decades - having the horn in question specifically designed for annoying people just makes his job easier. Combine this with hardcore cyclists' tendency to be extremely vindictive, and you have a recipe for ruining someone's life.
AFAIK, all of the above goes double in Ohio.
Heck, I'd crash deliberately. You lose your license, I get a broken wrist or a sprained ankle....and a big lump of cash.
