My Bolt has a hand paddle behind the steering wheel that engages regenerative brakes (and only the regenerative brakes). I make use of it extensively. When in "single pedal" (where the accelerator acts as a speed selector, i.e., the car brakes when you step off the 'gas'), it's a lot more aggressive than just lifting my foot off the pedal, and when in "simulate an automatic transmission" 2 pedal mode, I find the paddle is easier than figuring out exactly where the threshold is on my brake pedal between regen and friction brakes.

I love my bolt, but I wish it allowed you to choose a less aggressive setting when using the steering wheel paddle. My old leaf had that option.
