I mean, yeah, 6c/mile sounds nice, but I just did the math on my 2008 Honda Fit, and I get 9c/mile. That's with the cost of gas/oil changes. I haven't had to do any of crazy expensive maintenance that you suggest one needs every 3 months, and my oil changes are $50-60. The car has been paid off for about 8 years now. Sure, I've had to change the brakes and the tires once in a while, but those are expenses that even EVs have to deal with.
So my Fit costs me roughly $2700 to get 28000. Sure, not as impressive as the Tesla, but not really the money dump of your Lexus.
I think the break down for those who argue for EVs is that they typically compare luxury cars to EVs because EVs are priced similar to luxury vehicles, when in reality, most people want a car that's reliable and affordable. EVs struggle with both of these.
