This deserves way more votes! Time and time again I see this they whip out and forget that now one side of their cars tires are on a snow patch and whoops there they go sideways. Or they have 2 tires on the rumble strip (Rt.2 I'm looking at you) break traction and endup in the guardrail or worse. I just toot the horn and continue on with the familiar friendly one finger wave:)
