> The cars will last much longer. 500k miles vs. 100k miles of a typical car for personal use. 500k is already a reality with Teslas (https://qz.com/1737145/the-economics-of-driving-seven-teslas...) and Tesla is working to make 1 million miles cars.

First of all, thank you for an interesting article! Looking at it quickly though, if I make some rough extrapolations from their data, it seems like most Teslas will have lost about 40% of their battery life by 500,000 miles. So I really think it's disingenuous to say that a Tesla can drive that long, when its range starts to make it significantly less useful, when replacing the batteries would cost more than buying a cheap car. Basically I think you are just exaggerating the benefit of longevity for electric cars.

That said though, the Tesla batteries are holding up better than I thought and I agree with you electric cars are better for higher mileage applications!
