My comment about A/C is that an EV can cool better at idle than a combustion car since the compressor has its own motor, and can be driven as fast as needed vs. a standard car where compressor RPM is tied to engine RPM. Even with a good system, when it's 110*f air temp, 120*f local temp due to all the idling cars and blacktop, and 80% humidity, it makes a difference.

Except that does not apply to modern variable displacement compressors, that have no problem making the adequate pressure even at idle speeds. Once the pressure drop has happened, and the bulk of the heat has been removed, they actually
back off the duty cycle. Again, cold is cold, the evap temps will try to achieve a "just above freezing' minimum temp. That is Automotive A/C 101, nothing new there. And again, efficiency is withing whatever margins are set forth by the manufacturer... so some are better than others. Old fixed displacement compressors and engine driven fans (like my truck mentioned above) are indeed tied to RPM, so that at idle, they are NOT the most efficient for sure. But all that means is the system needs to be designed with greater margins in mind, so that at idle speed, the system still works in an adequate manner.
Most hybrids have electric compressors too. Their A/C is no better or worse. I think the big advantage an EV has, is (so long as you do not mind the battery use) is they can pre-cool or maintain a temp while the car is parked. And be controlled remotely and securely (meaning the doors can remain locked) via a smart phone or some internet based deal. Although you can do the same thing with an ICE car. Our one service writer starts his new Acadia from inside the shop about 10 minutes before he leaves. So once he walks to his car, it is already cool/warm. It does however require the HVAC temp be preselected beforehand, you cannot change that remotely.
The EVs are far more likely to be able to have a better A/C system capability simply because they are not having to content with all the waste heat of an engine, which is considerable, since most of an ICE's fuel burned turns into heat. So, assuming the engine is at the front of the car, means the firewall is hot. The underside of the car gets hot (exhaust routed all the way to the back), and, in most VAG products' case, the heater box is [very] hot. But, again, cold is cold, so even with all that, my Golfs and Jettas have ALWAYS been able to overcome that and keep the interior comfortable. I never, ever, have to keep the temp knob on full cold, even sitting in traffic should I have to. The B5 Passats are not quite as good, but they use an orifice tube system, which is not as efficient at lower speeds as the expansive valve system. They also seem to wick a lot more heat up through and around the transmission tunnel for some reason.
