Honestly the cabin AC makes very little difference.

You’re right though, that’s how you set world records. If you drive an EV at like 10 mph you could go a pretty insane distance. But no normal person would ever do that.

Cabin AC doesn't, but Cabin heat can in older vehicles with resistive heating. Heat Pump heating in newer Teslas is in the middle.

Absolutely. Resistive heating is less than the motors doing work, but is easily noticeable compared to AC.
