I've never understood why somebody behind me on the road would care at all about what my political views were anyway. I guess I get it during an election, maybe (in a grammar school "inventor contest" which happened to be during the 1980 US presidential election, I invented a bumper sticker sleeve that attaches to your car, so you could swap out political bumper stickers after your candidate lost. I didn't win the contest.) But in the end I don't really understand putting any sort of social signaling of any kind on my cars, though it seems hard to avoid even by just the kind of car you drive.

Closer to topic, I've always thoroughly enjoyed my trips to Canada, and can't imagine why people think "it's just like the US, so why bother" as seems to have been expressed ny some in this thread. I somewhat recently drove up to Roberval, Quebec from my home in New England, and it was absolutely nothing like the US. I find the rural Quebecois very odd, refreshingly direct, and enjoyable to hang out with.
