Lectured again by non owners on battery life

So lets break it down. First my original 2012 Nissan Leaf battery was only really useful for 6 years - luckily Tesla came along. That Leaf started with 85 and in 5 years was basically 40 in range. So yes pick the wrong chemistry and you may have a short lived car. I really want at least 10 years out of a car - especially at todays costs. First my Model 3 warranty vs my observed performance. 8 years or 120,000 miles on the Model 3 long range to still perform with 70% battery function. I have 52,426 miles at about 46 months - two months shy of the halfway period of the eight year warranty. My car was originally chargable to 310 miles. Somewhere around 2020 Tesla unlocked a little more - 315 on new cars although mine went to about 312 as the two year mark of ownership arrived. Here at almost 4 years I'm seeing almost 3% cumulative down or 9 miles off the 315 new mark - I can charge to 306 miles. So yearly about 3/4ths of a percent degradation a year (A little less if I properly did out the math but it will do). Now Tesla's warranty is about 3.75% a year degradation of less. Ben Sullin's Teslanomics had a bunch of stats showing across many Tesla owners the highest amounts of battery loss were in the early years and tended to plateau after so I'm guessing this rate of loss mat very good news for my car. Basically at 63, my car will almost certainly outlast me even in my 90's. Even at 75% - 235 miles of range at my age 100 and the cars age of 37, it will make a fine robofleet car as it has FSD. Then it can earn enough in my portion of the fares to buy a better flying Tesla if I'm still around. Luckily the plebes can't see me roll my eyes when they moaning 'but the batteries!'. For Nickola's sake talk to a Tesla EV owner.
