A few days ago I was pondering about repairing Teslas. With their continuous innovation it must be hard to get the right parts for the one you are trying to fix.
“Back in the day” I did a lot of work on my cars and those of friends. Japanese car companies were known for mid-year design changes to make things better, more reliable, bug fixes, etc. You would need to bring your VIN when ordering parts to ensure than you got the part right for your car. I am sure it was extra overhead for the manufacturers, but it also gave me a sense of security that problems would be addressed when they learned about them, not when they got around to them. TSLA can do this too if they want.
I am more concerned about the longer term transition for drivers/voters from a car that you can gas up in 10 minutes within a mile of wherever you are versus a car that doesn’t save fuel money when adding in cost of public charging stations, a car that weighs more than petro-cars and costs more. TSLA is the best of breed, but the breed has some endemic problems.
