OK, so I'm new to the EV scene. I can't find, in all that Hyundai docs that they provide, an overall explanation of when to incorporate the RG system into my daily driving. I'm gathering that it be primarily used during braking. Should I have it set at 1 all the time, and increase to 2, or even 3, during braking? If not braking, does being set at a constant 1, say on the highway, create drag which uses more energy, and offsets an possible gain via regeneration? TYIA!
