Midlana has provided me with a large amount of data on human nature. The most striking is the Harley versus sportbike rider ratio. This all happens during backcountry twisty 2-lane drives, so the Harley's are cruising, while many of the sportbikes are really pushing it (think: full leathers, dragging knees around corners, and with support trailers here and there!). Over the past five years I've kept an informal score regarding the "thumbs-up/low-down two-finger thing" Midlana receives in passing. From a database of probably around 500 Harleys and sportbikes, the score is: sportbikes, around 100.... Harley riders, 1 - one, no kidding.
I've had a long time to come up with theories and none are flattering to Harley owners, most involving jealousy of attention, feeling challenged, being ignored as a child, etc. On the other hand, sportbike riders get really animated, with very enthusiastic thumbs up. When I stop at cafes where both sets of bikers group, the car gets surrounded by sportbikers asking a dozen questions, while Harley guys pretend it doesn't exist.
Other datapoints:
I live near a state college and have evidence that the universe/supernatural power has a sense of humor. Back when I was in school I was invisible to girls. Now that I'm married and old, it's sad that only now do I drive something that gets their attention (yes, I'm fully aware that what they're seeing isn't me). The last time, three girls in a convertible pulled up alongside giggling like girls do, and one yells over, "Your car is sick!" So, either that was a good thing, or the car was leaking again, I wasn't sure which. Oh, and most kids think it's cool.
Lastly, I'm always surprised how many people don't notice. I'll stop at the front at a 4-way light, everyone just sitting there, and admit I'll watch people through my sunglasses to see if they look. I don't mean that as "how can they not acknowledge my awesomeness", I mean it as "how many here are oblivious to such an unusual looking car?" I guess it's a sign of the times, where everyone either messing with their phone or is lost in thought about all their life issues. And so it goes.
