Brave the cold my friend. Keep your jacket on, keep your gloves on, and drive with no heat. Not only that, you need to crack the front 2 windows 1/2 inch to prevent fog.
The good news, you'll probably get home on EV.
The bad news, its a cold ride but you know what, its just like being outside I got used to it and its not a huge deal. FYI my coldest ride in the cmax in the winter was at 9F and even my wife survived it. After that, any warmer temp felt like a cake walk.
You may use the heated seats with no issue.
Of course on longer trips where the engine has to start, you can use heat but remember to wait until engine coolant temp is 1/2 way up to the operating temp range, otherwise you'll burn hvb assisting the engine to warm up the coolant.
