Let me give you my testing results, from tonight's drive, in various modes/1pd options, braking, and CRUISE:
A) 1pd is an additional 'Mode', on top of either the underlying NORMAL or SPORT Modes, BUT, in reality, it is a MODE ALL IT'S OWN: It is designed to bring the truck to a stop, when you come off the GO pedal.
This means that no matter the underlying mode, when 1pd is activated, IT WILL apply the MAXIMUM amount of REGEN, and will also IMMEDIATELY start braking.
: : the brake lights are the indication that 1pd IMMEDIATELY starts applying the brakes. It does NOT 'wait' until a certain point - it is immediate, as your brake lights will indicate.
: : the amount of REGEN that 1pd applies is the greatest amount of REGEN the truck can provide, no matter the speed. You will see this immediately when you come completely off the GO pedal. Whether 25mph, 45mph, or 65mph, the REGEN is the same in each case, and the braking to go with it. If you wish to 'customize' this amount of REGEN and braking, keep 'some' pressure on the GO pedal, or 'feather' the pedal, slowly, or as needed.
: : as above, the 'amount' of braking can be feathered by the amount of pressure you apply to the brake pedal. ANY amount activates the brakes, and the brake LIGHTS.
Yes, the 1pd mode 'might' apply a CONSISTENT and INCREASING amount of braking as the truck is coming to a slower speed, but the brakes are applied AT THE MOMENT 1pd is activated.
You will see this proven by your brake lights, anytime you come off the GO pedal while in 1pd mode.
You will NOT see brake lights when you come off the GO pedal when either NORMAL or SPORT mode, ALONE. No braking is activated since only REGEN is applied by these modes.
B) 1pd MODE could be a 'MODE' all it's own, but since you must choose a DRIVE MODE when you put the truck in gear, or allow the NORMAL mode to default as the Drive Mode, you have to then ADD the optional 1pd ACTIVATION to either of these modes. 1pd is NOT an option for the other modes.
C) Choosing to use 1pd mode, or not, is really only a choice of the driver.
It does NOT create a more efficient travel, overall, over the long term, because the braking that happens automatically every time you come off the GO pedal is also robbing the momentum already built up.
Applying the physical brakes while in only Normal or Sport mode aren't going to create any 'better' outcomes, either, overall, over the long term.
It's really only a personal preference.
-If you like a smooth, easy drive - use NORMAL.
Very little REGEN, but You'll need to apply braking often.
-If you like a smooth drive, but more use of the GO pedal - you SPORT.
Much greater REGEN, and You'll use the brake pedal a LOT less often.
-If you like an AUTOMATED slowing and braking almost ALWAYS - add 1pd to either of those.
-If you like a blending of SPORT and NORMAL, use TOW HAUL mode. It doesn't matter whether you are towing, or not, it's just a blend of those two modes - middle of the road REGEN.
CRUISE CONTROL:
Interestingly, when in CRUISE CONTROL, you are effectively telling the truck to manage ALL driving speed, braking, and REGEN, all on it's own.
Your DRIVE MODE does not matter while on CRUISE CONTROL. You are allowing the truck to control this.
Your 1pd choice does not matter while on CRUISE CONTROL. You are allowing the truck to decide when to REGEN(slow) or STOP, if traffic ahead dictates.
Now, if you apply the BRAKES yourself, while cruise is active, you are effectively turning OFF Cruise Control, and your underlying Drive Mode, or 1pd option, will dictate how the truck responds when you then come off the brake pedal, and until you reactive Cruise Control.
Not sure why you wrote this diatribe, this isn't what was being discussed. We are well aware of how 1pd works, how cruise works, etc. None of those were being discussed.
But again you are wrong.
First, the brake LIGHTS are controlled by the computer and come on whenever slowing at some rate regardless of regen or physical brakes.
Second, physical brakes are NOT applied in 1pd nor are they applied when the brake pedal is pushed. Physical brakes are applied when requesting to slow more than regen can provide. You have flipped flopped on this multiple times now.
