Well, you are making some assumptions. Who cares if your car starts, its worth more in pieces. Putting it on a flatbed is faster, easier and looks more legit. Second, you just posted that you own a gun, where there is one, there is more, now someone seeing your tag number gets your address, waits till you are gone and you can imagine the rest. We all know how easy homes/cars are to break in/steal, etc. Criminals prey on opportunity. The more you present, the better your chances are for being taken.
For those thinking you can't get an address from a tag number, time to wake up. A google search and $30 and you are in business.
