Try that here in Ontario in mid January, at about minus 20.
With no engine temp and no heat, your feet will freeze to the pedals!!
Last winter I had to wrap my Bonneville radiator in cardboard so it would warm up!!

Yeah, I have family in Toronto and Quebec, I would not try it there. btw I also had to use the "cardboard heater" so I could defrost my windows.
My very proper Canadian wife really loved this shadetree fix.

$100 for that supercoolant is a little more expensive than popping a thermostat out. But I am glad to know about the stuff in case I ever build my own tow mule.

If the proper head gasket and sealant is used, heat shouldn't cause abnormal issues. They already make the trip from 0 degrees to 220, so another 40 degrees shouldn't make too much hassle

Another big help is proper head bolt/stud arrangement. That's dependent on design, so some cars will always have problems regardless of temps.
