On top of that, it probably doesn’t help as much as just making the engine/vehicle more efficient overall. I think there should be more focus on hybrids in the meantime as well. As for ac, it would be nice if there were more electric AC systems in traditional vehicles. Near instant heat/cool and could be enabled with the engine off with a suitable battery for extended stops like when parked.

I am fine extending the 2035 date if it is unrealistic, but we need a goal. Range anxiety isn’t so much about range as it is about charging time to get back on the road as well.

Electric A/C, maybe. But in anything with a gas engine, it really just doesn’t make sense to have electric heat, since the engine is already such a prolific source of free waste heat. And waiting a minute or two for it to warm up is a small price to pay for the massive efficiency of having all your heating energy being basically ‘free’.

Would only make sense in hybrid vehicles, IMO, since they already have a large battery that could be used for this.

Hybrid vehicles already make much better use of engine start/stop anyway.

But electric A/C and heat are already becoming fairly common on hybrid vehicles, I think – especially on plug-in hybrids or ones with an ‘EV mode’ that can drive on electric only for a limited range.
