Well, in defense of cliffracer (I know, not a good cause) they only really start appearing and getting annoying once you're out in the ashlands somewhere. The Grazelands, Ascadian Isles and Bitter Coast... practically no cliffracers whatsoever. Me, I
loathe the ashlands and am, for entirely inexplicable reasons almost phobic of dust storms (probably because I mistook them for Blight storms early on in the game, and confused Blight with Corpus... hence the fear that remains to this day

); hence I very
very rarely venture out into the dreary lands of ash and have a largely cliffracer-free existance.
