Most new EV models allow you to set a “leave time” for when your car needs to be fully charged, with a warm battery and a pre-heated cabin. For example, Tesla owners have the ability to "precondition" their car, which entails setting a time via the Tesla app for their car to pre-heat.

Many people pre-heat standard engine cars in the winter, setting an app isn’t really that much different and arguably more convenient.

It's a stupid argument to be so concerned over power being used when ICE are ridiculously wasteful. In a standard 50L tank 30 liters literally goes to doing nothing other than getting hot. If your EV is pulling 60% of the total energy bill to keep the battery warm you have other issues that need looking at.

Just out of curiosity are you clutching your pearls over the clock drawing power while your car is parked too?
