That's very true, but both ultimately have the same end effect: "Lost range". But can be mitigated by caring for them differently.
In the case of the EV, it's leaving it plugged in and in the case of ice, it's adding de-icer to the fuel. You just care for it differently. Arguably the EV still is a slight advantage since traditional engines still need to be warmed first whereas the EV can just start and go as long as it was plugged in overnight since the heater pads on the batteries will make sure it won't drain too quickly. Can't keep a fossile fuel engine running all night like that.
