Twice in the last couple of weeks I've met SUVs in my lane while riding my motorcycle, once 3/4s of the way in my lane (in a curve on a hill), and the other time 100% of the way in my lane while I was carrying my wife as passenger. Both times they were women on their cell phones, apparently completely mentally removed from the world in which they were navigating a heavy weight motor vehicle down a road at high speed.
They weren't young women, though. Both of them were about my mother's age. The second one shot us the bird after she wrestled her car back into her lane, as if she was deeply and personally offended that she'd had to leave off her pleasant conversation for an emergency lane change. I assume the truth is that she was embarrassed and defensive. Still, it's a good thing my wife wasn't in control of the direction of the motorcycle on that occasion. To judge from her commentary once we got to town, she was ready to rip that woman's lungs out and salt them.
