I didn't get the bit on turning regen "down" on icy roads. I see the case for safety, although I'd think "engine braking" (ie recuperation on overrun) is safer than user's own hydraulic braking even with ABS. I don't see the case for efficiency; coasting is more efficient, but that is generally valid, not sure what is specific to icy roads. Are they implying regen losses are even worse on ice, since there is more (micro)slipping/sliding?

My guess is they are assuming that everybody uses 1 pedal driving in EVs so reducing the deceleration on liftoff will reduce the likelihood of under-rotation.
I think the Porsche system is unique(ly good )
