Jip. I drive from Witbank to Centurion everyday. Monday was pretty bad, but luckily I missed all the accidents.. My wife works in the casualties dept. at a Witbank hospital, though, and she described a warzone!
Yesterday was fine, but this morning I delayed leaving by about an hour, in order for the mist to clear up a little, and I do think it helped. Now I just need to catch up on my morning work!
