Tesla has this and it feels like a safety issue that Rivian doesn't. If one-pedal regen needs to reduce or stop due to heating or battery SOC, please add an option to maintain deceleration feel/behavior by blending in actual brakes.

Deceleration behavior when taking off the accelerator should not change randomly. If regen cannot slow down the vehicle as it normally would, please please maintain the same deceleration with a brake.
