Because much of the stated reason for EVs is the money you'll save on fuel and maintenance costs, so spending extra money on something you'll use once per year doesn't fit the money saving narrative.

Ultimately, what I and the other commenter is saying is a once a year "need" really isn't a need at all. To further my example, if I lived in the snow or traveled there regularly, then AWD is likely a reasonable expense, but if very rarely used it would make more sense to rent/borrow. Same goes for a truck (for hauling), or gasoline car for the range.

I drive an EV now and my next car will likely be an ICE AWD vehicle. But I'm also aware that it's not the most economically sound decision and I'd be buying it for fun. Under no circumstances would I be justifying it by the longer range (which I very seldom need) or to travel to the snow.
