They dont seem to actually last 10 years though. Sure, in an old Prius you only care about the battery not being completely shorted out, and the price of battery degradation is slightly worse fuel economy.

However, every time I look at renting a Tesla on Turo, each and every example has reviews with stories about not making 100 miles to the next stop on their trip. These are cars that are only 3-4 years old, not 10.
