I understand the purpose of ABS. I also understand its effects on unskilled driver stopping distances. On a car, on wet pavement, being driven by somebody who doesn't know what threshold braking is much less how to do it? ABS will almost certainly reduce the stopping distance vs what the same person would have been able to do without it. Seeing as how it turns "4 wheels locked skid" into "maximum use of available traction for braking", what do you expect the result of ABS engagement will be in the situation I described above?
