Where I live you almost never need an airco.
I did in my professional life about 75,000 km (50,000 miles) each year and have never been in traffic jams for more than 1 hour.
In EU we don't buy these big V8 tanks that consume huge amounts of fuel. I need 7 liter per 100 km ( 33 miles per gallon), driving many times at speeds around 180 km/hour (115 miles per hour). f I would drive that way an EV, I would need to recharge my EV every hour.
I think we even had no snow the last 8 years even not in winter. So heating is almost never needed.
Even using airco, music and lights on, my car can easily run 24 hours stationary to give the required energy without refueling.
Biggest and real problem with EV's:
A Tesla at 200 km/h is completely empty in less than 1 hour driving.
On the German autobahn I beat any Tesla with the Mini Cooper Diesel of my wife at that speed if the trip is longer than 200 km.
