Thats basically correct. Regen level is handled differently by each manufacturer. All? except Tesla? allow the driver to set the level to their preference, so that when you lift off the accelerator the vehicle will slow more or less aggressively depending on your setting.
One way to think...
I didn't see it mentioned...just assuming the heating and AC will be via heat pump?... maybe with some resistive heat back up for the really cold climates.
