The real question is what century are we in? Oregon and NJ are in the first half of the 20th apparently.
Funny, I know that the gas filler thing is truely random...but my Olds, my wife's Sebring, Chevy Silverados/Colorados/S-10s and a Ford E-150 at work...basically every vehicle I've touched in the past couple years all fill on the left. Actually, I've driven my mother-in-laws Taurus and tried to put gas in it once, but she had one of those friggin locking filler caps and the key wouldn't work, so it being on the right didn't end up being an issue. Speaking of power window buttons, I drove a rented HHR for a couple days, and it took me a solid minute to find the window buttons while driving. (they're between the front seats). My 80-year-old dad went with me when I dropped it off and I bet him a buck he couldn't figure out how to roll the windows up. I won!
