If You’re hydroplaning, You are effectively losing forward momentum relative to the road.
However, You’re drive wheels will still be near the set cruise speed. The drive wheels (if hydroplaning) are effectively on rollers at that point, no? So, the CC would not accelerate greatly me thinks.
IOW: If You are on (thick sheet of) ice, and You gradually spin Your drive wheels (which are also the wheels with the VSS) upto 30mph, You can theoretically set the CC @ 30mph… as the wheels slip on the lack of traction the CC will accel or decel to maintain the 30 mph.
