Ummm car alarms have there own horn for one. Two most stock cars with keyless entry honk the horn to tell you its locked. Your bitching about people using a feature every auto maker installs.

Agreed. I used go to this coffee shop during college and older people, who didn't go to that school typically, would lock beep-lock their cars, which when it's sat 4 feet from me and there's a brick wall to exaggerate the echo, can really disrupt your studying. So I started parking my car right in the front so that every time someone did this going in, I'd hit my car alarm going out and scare them half to death.

just the lights
