When you leave a voicemail and expect a callback, DO NOT leave a long rambling message describing the problem, then rattle off your phone number like a lawyer in the last two seconds of a used car commercial. Say it slow and say it twice. I may not be ready to copy the first time, and if I have to start the voicemail and listen to the rant again, I'm gonna be annoyed. And that's going to delay the response.
Two, if you're tailgating me down an eight lane freeway (4 lanes each direction) honking and generally acting like a jerk is not a very good way to get me to speed up or move over*. I'm already 6 over the limit and passing a car in the next lane. You have 4 lanes to choose from, pick a different one.
This is especially a bad thing to do when I'm headed to the range and have several weapons to choose from. BTW, given that I was fairly lightly armed today with only a pair of .22s and a 9mm, which weapon did I reach for? Answer: None of the above, not even the proverbial middle finger salute. I reached for the cellphone. Once he figured out I was dialing 911, he found another way past me two lanes over with nary even an evil glance.
Sometimes just the threat of a 911 call is enough to end a tense situation. When it's not, what's your plan B?
* My general attitude towards faster drivers is "Hey knock yourselves out. Go find those DPS officers laying in wait. " I always like a blocker if you get the Burt Reynolds reference.... Just come up easy and I'll move over as soon as I get to a safe place to pull over. Then you can take off and attract all the unwanted attention, letting me cruise on by while Officer Friendly writes you a ticket.
PS.. I need to find that old digital camera and keep it in the car for just such occasions...
