I've started noticing a few MINIs that I see regularly on the way to work and I can't get a wave. There's a chili red that drives the opposite direction down Lincolnia, I can't imagine they don't see me waving.
There's a purple haze with fat white stripes that comes into DC with me on 395, I'll give her a break as I always see her in the left lane right near Pentagon or on the bridge, it's kind of crazy around there.
I saw 5 MINIs on the way to work this morning and not a single wave, but the guy in the yellow one did look like he might have waved if I wasn't zipping by him so fast
