Thanks for your candour. For what it's worth I absolutely agree with you fundamentally there is no reason an EV shouldn't be able to make the million mile mark with only modest maintenance (perhaps having to replace individual components of the motors, perhaps a bearing for example). Fundamentally they don't have points of sliding friction, this makes wear and reliability much easier to achieve.

What impact this would have on the battery is an interesting question but with modern temperature control and BMS systems it may not even be a deal-breaker.
