Yes, because that’s how regenerative braking works. This was discussed at length in the linked article.

That sounds dangerous. By comparison the Prius uses regenerative braking when you hit the brake, but if that isn't enough it will switch to normal (friction) braking. Having something that switches from braking to no brake without warning seems like ... terrible design.

  A Prius performs light regenerative braking whenever you're not depressing the accelerator; it primarily uses regenerative braking when using the brake pedal, but will switch to the friction brakes if you brake harder than the power train can move energy back into the battery or the battery state of charge is at the upper limit.

  The Prius also has a one pedal B mode though which sounds similar to the L mode in this Bolt.

    That's just a low-gear mode, like putting an old 3-gear automatic in 2nd gear, to engine brake downhill.

  Uhhh, manual cars have worked like this forever. In first gear especially the braking when you let off the gas is enough to be jarring if you're not gentle

    Yes, but there is no computer turning mechanical engine braking on and off based on some set of non-trivial conditions.
    - slackingoff2017 9y ago
      Ehhhh that's not quite true either. Above a certain rpm the engine cuts fuel completely and engine braking is strong. In cars with electronic throttle control the computer might also open the throttle to maximize energy consumed compressing air. As you pass through that cutoff range the engine starts firing again, maybe 700 rpm above idle. Engine braking stops being effective when this happens. Also, newer cars don't do a full fuel cut when engine braking with a cold engine or if the catalyst is getting too cold to work. So sometimes engine braking isn't very strong. Basically you can't rely on engine braking so when you're doing it your foot usually hovers on the brake pedal. This isn't any different than the hybrids

        #carbureted4life Whatever the case, I've found engine braking to be fairly consistent in manual transmission cars at a given speed/gear. But, I've never thought I could rely on it to bring me to a stop in a parking lot. It blows my mind that an EV driver would think that.

No, actually, since it's unclear how much braking regeneration will provide, when I brake I start by taking my foot off the accelerator but if I'm at all in doubt, I'll put my foot over the brake. Also, since Tesla regenerative braking always turns off below 5 mph, I always have my foot over the brake pedal at low speeds.
