I usually leave it in D and use the paddle. But only with the brake pedal can I completely and smoothly modulate deceleration.Staying only in strong regen mode gets tiring fast because you have to hold your foot halfway down on the accelerator pedal for half the time. I used to do that. The flipping of the "shifter" was the relief.
I think this is a must, and if I'm not correct, Tesla does not have it.Also, note that braking with the P2 (up until a pressure point) does increase the regen strength rather than invoking the friction brakes (some other EVs only use friction braking entirely). So you can still increase regen but it won't be with one peddle driving.
The sw blends the motors with the calipers. Those are the 2 braking components. The pedal first engages the motors for regen, then as necessary (through a sw algorithm) the calipers are engaged for friction braking.You're the first one to claim that modulating the brakes for regen in the Bolt is fairly easy. I couldn't disagree more, especially compared to simple L mode toggle and letting the main traction motors do its thing.
You're also contradicting yourself in "calipers don't do regen" then "software blending in the calipers only..." Whatever the specific brake component is called, it's not the main regen of the motors without touching the brake pedal.
