The bad thing is, even if you see the moron barreling down on you in your rear view mirrors, you're never sure which way to go to get out of the way!
I've pulled off to the right...and had the car attempt to go around to the right at the same time....
Dunno. If you notice this happening, you don't really have much time to decide what to do.
I almost got rear ended in my pickup truck a couple of weeks ago.
I saw it coming, and almost pulled over onto the shoulder to get out of the way. An early 80's era large GM car was doing 35 or so, and ready to plow into me, as I was doing 5 mph or so in stop and go traffic.
After she stood on the brakes, and started sliding, she headed for the shoulder of the road before I could.
