Actually it is disengagement always = Intervention but not always the other way around.Intervention = disengagement when comparing to a driverless cross country summon, or as near as makes no difference at least from out here in the cheap seats.
Any drive with either is just boring, so what, call me when it's actually zero.
Many times my patiences is challenged and with the Go pedal right under my foot I can't resist even if FSD would do about the same thing in another second or two. Maybe it's me that needs an intervention.
