Had friends in from out of town over Christmas, trip was ~3,000miles round trip. Their EV didn’t mind the trip, her aging bladder needing emptying more than the EV needed to charge.
All of the Tesla models have AWD options, but are far from an ‘off road vehicle’. If your wife needs true 4x4 for some rock crawling, mud bogging, or high clearance as part of her trip then obviously a different vehicle currently fits the bill. Or if range isn’t currently supported by chargers on the route, of course.
The $2.50/ day is a pure ‘fuel cost’, no depreciation or maintenance (basically tires)
I could run the comparison to my Ram 3500 at quite literally twice the purchase cost of the commuter EV. Operation of that beast beyond its hauling and towing duties for communing would be insanely expensive (~$45/day on just fuel, and the list of maintenance and regular wear components on that goat is long, I should know, on my 4th diesel Ram).
Part of the difficulties of comparisons is the subjective component of ‘equivalent commuter car’. My comparative vehicle would probably be a 3 series BMW or similar. I wouldn’t compare to a Honda Civic or a Hyundai Tiberon to my current commuter. IE purchase price would probably align and not be a significant component in the math.
