For the second time in three months, I got rear ended last night. Both times it was me stoping for traffic, the guy behind me stopping for traffic, and the guy behind him not quite stopping. Just a love tap to me both times, but, Jeeze, pay some friggin' attention guys...
If you're getting rear-ended, a Crown Vic might not be the best choice. While they're not nearly as bad as a Pinto or those old Fords that had the "drop in" gas tank, they're of a design where the gas tank is a bit vulnerable.
Now at a quick glance, you'd think they'd be safer because of the gas tank location. The tank is still behind the rear axle, like any other RWD car with a live rear axle. However, while most cars just strapped a flat tank on underneath the trunk, the Crown Vic has a more vertical, upright tank. It sits right behind the rear axle, and in front of a deep-well trunk. The rear edge of the tank is further from the rear bumper of the car than in something equivalent from GM or Chrysler (although GM quit making cars "equivalent" to the Crown Vic in 1996 and Chrysler stopped way back in 1981!).
However, in a rear-ender, most cars tend to buckle right over the top of the rear axle. This is especially true of body-on-frame cars. In the Crown Vic's case, the gas tank gets pinched between the rear axle and the deep well of the trunk and ruptures.
Now, in the real world, I think you have to rear-end a Crown Vic at something like 70+ mph to make the tank rupture. It's somewhat common for police cars to get rear-ended at high speed when they're stopped alongside a highway, so this was a legitimate concern for police officers. That's the main reason that the Crown Vic got so much bad press for the exploding gas tanks.
So Brewer, if you want a Crown Vic, go for it. Just don't camp out alongside the highway in it!
As for tailgating, I've actually had people get up close enough behind me when I'm driving my pickup that I can't even see them in my mirrors, with the sole exception of perhaps a sliver of roof just barely peeking out over the top of the tailgate.
