I have a Volvo hybrid where the AC continues running even when the main ICE is off(as long as you have charge in the main battery pack). It's honestly fantastic.
Hybrid (or PEV/BEV) car's electric A/C is heavily underrated feature compared to pure ICE cars. Idling engine only for A/C seems to really inefficient. I think every police cars should be at least hybrid, but still not here.
Toyota Hybrids do this too and it’s an incredible experience to sit in a parking lot blasting full efficiency AC with the engine off. I’ve heard of people camping overnight in their Priuses this way with minimal engine use.
