ABS is there more for when you panic brake or there something on the road surface...
Examples would be
A Car pulls out right in front of you or a car in front of you jams on it brakes in the wet and you just automatically just grab a hand full of brake in panic mode
Or like what has happened to me more then once while braking
I have hit mud patches, sand patches, gravel patches, wet leaves, fuel/oil patches, wet drain covers, wet painted road lines/signs etc etc
