The explanation I saw in another conversation was that certain settings (I think one-pedal driving?) for regenerative braking make it feel like you’re constantly switching between accelerating and braking with no in-between. Like as soon as you let off the accelerator the brakes come on, no ability to just glide along, so it feels very lurching. I love the idea of recovering power from regenerative braking so I guess if I get the chance to look for an electric car someday I’ll have to make sure it can be configured to just happen when I actually use the brake.
