Those are fair requests, thanks for point that out. For the leaf, it's just true that they designed a very poor system for battery reliability in retrospect. All modern EV cars have a battery heating and cooling system that protects the battery and helps protect the mileage. I've had 3 evs now over 10 years, all 3 had battery heating/cooling. My first car from 2012 was driven about 50k miles over 3+ years, no noticeable loss. My second ev is now 8 years old, has about 5 miles of loss over 68k miles (something like 272->268). It's been driven a zillion times between my city and a ski area, about 130 miles round trip. My 3rd one is pretty new so too soon to know. When you supercharge these cars (with a dcfc), with a high amperage high voltage charger, heating in cold weather or cooling in warm or normal weather really reduces wear and tear on the battery and keeps battery life good. It's just the case that the leaf did have this serious problem - there must have been one or 2 other cars without battery management systems, but the leaf is the only one that seemed to sell in large quantities.
