> "instead of applying engine breaking when the driver takes their foot off the pedal, they went to great lengths to _move the break pedal_ in proportion to the amount of engine breaking that is currently being applied as per the VCUs command" Regenerative braking slows the car more aggressively than an ICE where you take your foot of the gas, so the pedal change isn't putting on the brakes, it's communicating to a driver used to ICE that the car is slowing more than might be expected. There may also be a sports-related reason for people who habitually left-foot brake.

You clearly have never used a car like that. You develop muscle memory for where the pedal is - finding that the pedal is not where it used to be does not inspire much confidence. Every other manufacturer has managed to control regen breaking via throttle modulation - even ICE hybrid cars have been doing that for ages.

  I've used left-foot-braking in my (ICE-powered) daily driver for years. Regenerative braking is very different to taking your foot off the accelerator in a conventional ICE car, it's much more powerful a stopping force than traditional engine-braking. I understand the rationale for moving the pedal to illustrate the amount of "braking" force. I'll admit I'm not exactly a typical driver though.

    Why not move the gas pedal too, when using cruise control then?

      > "Why not move the gas pedal too?" I'd support that. It does feel unusual in most cars' cruise control that you can push the accelerator to three-quarters of its travel before you start to accelerate (e.g. if cruise control is at 50–60mph). If you push the gas pedal, you'd expect to go faster, wouldn't you?

      They used to, but not by design. Back when throttles were still cabled I could feel the cruise control doing its thing by lightly resting on the pedal.

It depends how much you draw from the motor/generator. One can modulate it as they want, whatever can't go into the battery due to chemistry or drive constraints can be disposed of as heat.
