Black ice on the 400 a few weeks ago (which you can see..it's not like it's some invisible monster that sneaks up on you....when it is below 0 and the road is reflective..you're prob. on ice...anyhow) dude in a GMC Savanah blasts past me and as he's getting out of view ahead goes spinning into the guardrail...everyone else is doing 60 with their hazard lights on and this dude was oblivious....Darwinian selection me thinks
