I don't have time to dig into it, but $0.50 seems like a wishfully low number.

Doesn't take too long to prove it is too low. Lets say this fancy self-driving car cost $50,000. Lets say it is expected to go 250,000 miles in its lifetime. That is $.20 per mile! If it cruises at only 25 mph, that is $5 in wear and tear alone! Even if you slash the price and up double the life of the vehicle, you are paying more than $.50 an hour.

  That's a very simplistic analysis since it ignores the difference in wear and tear between cruising at low speed versus driving at normal speed. A car that's built to last 250,000 miles of normal driving can likely go much farther at low speed cruising, especially for an EV.

    I don't know, that low of a cruising speed suggest a lot of stop and go driving. Even if true, the analysis was meant to be a simple refutation of the $.50 per hour claim, and I really doubt you can increase durability enough to tip the balance. And that doesn't even include regular maintenance- lubrication, tires, brakes. It doesn't include electricity. It doesn't include damage, insurance costs, etc.

      When the traffic lights can coordinate with cars, they can avoid the need to stop, at most they may just need to slow down, which can be done without brakes. An EV doesn't need (much) lubrication, for example, the Chevy Bolt EV maintenance schedule has only tire rotations for the first 150,000 miles: https://www.cnet.com/roadshow/news/chevy-bolt-maintenance-schedule/ https://www.cnet.com/roadshow/news/chevy-bolt-maintenance-sc... With low speed travel and minimal stops, there's not much tire wear. Ubiquitous EV's should reduce the accident rate dramatically.

  Realistically, the average speed of any car navigating an urban grid with stop lights/signs is usually going to be a lot less than 25 miles per hour. Maybe more like 5-10, even if it's not deliberately trying to drive slow.
