Yes, though most people don’t need to do that. Average miles driven in the USA per year is 13500, and this car (“in a desert”) would generate 12,000.

Yes shade, climate, etc. is relevant, but it’s also true that a significant minority of people just won’t drive the way you’re talking about. (Such people shouldn’t be spending 100k on a car, but that’s a separate issue).
