My method is real simple. I don't put it on vibrate, I just turn the d##n thing OFF!
My voicemail greeting has the following message after identifying myself - "If I didn't answer your call, it's because I'm eating, sleeping, driving, or at work, and my phone is turned off. Leave your message and I'll call you back."
My biggest peeve about cell phones? Let's just say I have been known to stick my head out the window and yell at another driver "HANG THE F##K UP AND DRIVE!!!!"
