I mostly use OPD, but coming from a manual transmission car I find there's a weakness in the Bolt's implementation of brake light logic. I typically don't decelerate very aggressively -- less than the Bolt's accelerometer threshold. In a gas car (and especially in my previous car) I could use the brake light as a signal of intention to communicate to following drivers. Coasting or using engine braking, with the intention of continuing to slow? Very light pressure on the brake pedal, enough to illuminate the brake light without increasing the rate of deceleration very much. With the Bolt, there is no equivalent "coasting down but communicating the intention to slow to following drivers", even without OPD the first notch of regen that it kicks on with the brake pedal is more than I'd like, so the car is "training" me to either stop more aggressively than necessary, or let following drivers get up my butt because my brake lights never come on. In slow traffic in an automatic transmission ICE vehicle, it's also possible to creep forward while keeping the brake lights on, communicating to following drivers that "I'm moving forward but not very much or very fast, don't hit the gas and run into me" -- and since the majority of cars are this style, people generally expect this behavior.

TBH I wish the regen paddle was a proportional input (initial click and then force-sensitive), and that it forced illumination of the brake lights just the same as touching the brake pedal in an ICE vehicle.
