Except that generally speaking, your gas tank doesn't really change capacity that much based on the weather -- the fact you have to idle it is obviously a concern, but typically your fuel economy doesn't dramatically change because the weather outside changes. By contrast, I've heard and seen an EV in very cold winter weather basically become a brick until it spends some time in a nice heated space, and then it only wakes up until you bring it back outside and the battery freezes again.

I've done really long road trips in extraordinarily cold weather. I used to live in the far north, and I still work up there occasionally. You're not losing 80% of your travel capacity or anything like that.
