The problem is one of psychology. Even for someone who drives 35 miles or less per day, most of the time
, the idea of a car limited to 50 miles or so is difficult to accept for the "mass market". That's why so many here are of the opinion that BEVs won't catch on until the range is substantially higher.
The point to the 4-bar 70% EOL (or even less) is economics. Batteries are expensive, the more miles you can get out of one the better off you are. The longer you use it, the more miles you get.
I agree and am attempting to figure out how to deal with a 50 mile range battery in the years to come. It is a difficult problem.
Should get about twice as many miles out of a pack to 70% 4-bar loss as with 80% 2 bar...
Sorry, I don't believe that for a minute. I've seen no evidence whatsoever that the battery degradation really does
slow anywhere near that much. One factor to consider is that a lower capacity battery requires deeper charging cycles to get the same miles.
