I got a used 2023 Chevy Bolt and initially disregarded one pedal driving was an absurd and unnecessary feature, but now I think I would skip a car that doesn’t have it.

Does the one pedal drive activate the brake lights, or why does it feel that a lot of evs don't show the brake lights when 'braking', which is really annoying when you drive behind them.

I've never tried it but can you explain why you like it?

The idea is a bit hard for me to comprehend because there are definitely occasions that I would tap my brake kind of hard and then immediately speed up again. Perhaps my mental model is still very much ICE engine and torque converter oriented and that's holding me back from understanding this. From an abstract point of view, it seems there is only one variable I'm controlling for, which is acceleration, so having two pedals is just doing the same thing with more steps (literally). One pedal should give me everything I need.

  • As you suggest, it smooths out your driving habits. You’re just focusing on balancing the accelerator with your desired velocity, that’s it. Need to go slower? Back off the pedal until you hit the mark. The regenerative braking kicks in so it slows down quickly, sort of like light-to-medium braking. It’s more responsive than you might think. Need to go faster? Press the accelerator as usual. No more going back and forth between gas and brake, which makes it less exhausting in stop-and-go traffic. You’re also maximizing regenerative breaking, so that’s increased efficiency and less brake wear. That’s particularly good when you’re doing down hill.

  • Anecdotally, to me it's just more fun. It increases range by relying entirely on the regenerative braking and relegating the disc brakes to an "emergency" role. For freeway driving in traffic it's also more intuitive, since you don't have to balance coasting/braking and can just ease off the pedal more to slow down quickly. Muscle memory can definitely be hard to break though, when I'm in a hurry I sometimes forget to enable single-pedal and drive for a bit before I realize it. The car we have (Chevy Bolt) has a separate regenerative brake control as a paddle on the back of the steering wheel for use in "regular" mode, but it's awkwardly placed.

      I'm not sure about the Bolt, but most EVs work that way, one-pedal or not. Even a hybrid Prius doesn't seem to use the friction brakes unless it has to (emergency, coming to a low speed stop).

      I don't like one-pedal on the Hyundai Ioniq if for no other reason than it uses both front/rear motors regardless. In contrast to Eco/Normal mode that uses the front motor only if it feels the need for moar power!!
