Getting back to what I said earlier, there is an issue of what ABS can do and what it really does in practice due to cost cutting measures. I.e., the ABS on my i3 is just ****ing awful. Straight line braking, it works great, but in a corner it is deplorable.

There are 3 and 4 channel ABS systems that don't have that behavior, but BMW used a 2-channel split, which is a hamstrung half-measure.

That said, ABS on the FUV could just as easily be the same configuration as a bike and be moderately decent performing. Though there would still be an issue of the inside wheel lift that would cycle the pump and simultaneously cut the braking on the outside front. So in my mind, if it is not 3-channel, I don't want it. It doesn't help me and would just add cost, weight, and complexity for virtually no gain.
How does BMW meet the federal mandate for stability control that brakes individual wheels with only 2 channel ABS? Can they split regen side to side?
