Maybe it will be the same for EV, but as I see it now, EV are far less owner-repairable than ICEV and can be dangerous to work on the drivetrain.

Something a lot of people don't understand is that lithium ion batteries will last hundreds of thousands of miles on average. Modern day 21700 cells (and others, that are put into modern day vehicles) are rated between 1500 - 4000 charge cycles, that means 450,000 - 1.2 million miles before it drops below 80% capacity.
It isnt the charge cycles, its the age and stress of the cell which kills it over the years, many packs are lasting 15+ years which exceeds the average 12 year car lifepsan. Newer batteries are even better, but data is limited
