I know I'm not the only one here old enough to remember the land yacht.
Back in the early 90's my sister drove a 1970 (ish) Mercury Grand Marquis. That car was 19 feet long (compared to my dad's old panel van at the time which was 16 feet long.) My sister, being in her late teens at the time, had on at least one occassion 13 people riding around in that car with her. LOL IT WAS HUGE
One day my sister is driving along, following a new minivan which is following a car in tow on the back of a wrecker. The wrecker sort of abruptly turned into a service station. When he did, the car became disconnected and rolled out in front of everyone. Obviously, everyone slammed on breaks and just sort of freaks out a little bit (because how often does a car fall off a wrecker on you?)
Little sis slams into the back of the mini van. CRUNCH
"The Tank" (my sister's car) plows into the back of that van crushing in the back of it about 2 feet. Thank goodness no one was hurt. The Tank didn't have a scratch on it. (not a new one, anyway.)
I feel safe in a car like THAT!

(Not with my sister driving, though. LOL) I backed into a parked truck one time (totally my fault) and ripped the whole front bumper off my corolla. Didn't smudge the truck at all.
I don't know all the statistics about BEING safe in a vehicle. But I know that I FEEL safer in one of the bigger pick up trucks (like a Silverado or such.) I'm not sure what it is about it. I think having all that extra space around me makes me feel like I have a buffer between me and "them." Funnily enough, when I was driving the Ford Explorer, I didn't feel safer at all.
Back to the price of gas, I filled up my car from empty the other day for $19 and something. At the height of oil prices it cost over $44.
