Today I'm paying all of 3c/kWh for electricity. Can't get much cheaper than that.
Also the EV+range thing is mostly negated by pre-heating the car while it's plugged in at home, warm battery = more range. Just like we need to do with ICE cars to make the engines even start in the winter.
As for winter, what you say may be good for people with a house and garage who are driving to work and back (but then range should not be an issue anyway). It doesn't work when you street park and it also doesn't really work when you're driving long distances or with a car that's mostly outside, like a delivery van.
