I shudder to think what would happen if I wrecked my Versa. I already came close once (couldn't see a damn thing through the fog, took the wrong exit, flew through a t-intersection... ALMOST hit a fence.)
Please, get off the road.
You ever driven in heavy fog?
Never go faster than you can see. Missing an exit? Maybe. Going through a T intersection and almost hitting a fence? Time to give the CrackerJack box its license back.
