How can you have a conversation about this while excluding maintenance, insurance, and gas? Those costs are the bulk of the costs associated with car ownership.
I was just going to post something similar.
If I ignore maintenance, insurance, and gas, I've had some vehicles that paid me per mile! Now, getting a cheap beater, throwing a good bit into maintenance, and selling it for more than I paid after a year or two of driving isn't actually getting paid to drive, but if I ignore all the stuff I had to replace, it sure is!
I don't know my exact cost per mile, and I {don't particularly care, don't want to know.} On the truck, it's obscenely high right now because I've been doing some maintenance on it (parts are expensive), and it's not driven much (since I don't drive it as a commuter, just for hauling large or heavy stuff, or longer road trips when we're bringing a lot with us).
My ebike cost-per-mile... oh, $3k build cost (not really, since I used the battery from the last bike), 50 miles/wk, 6 months on the current build... $2.5/mi and dropping? *shrug* On the other hand, it should last nearly forever, and lets me get to work literally quicker than driving.
This "What did you pay vs how many miles you've driven it, ignoring everything else" metric is slightly idiotic, and it only works "well" (creates a low number) if you put a genuinely absurd number of miles on vehicles.
