Granted they're dumping the fleet with degraded battery packs before doing the 15k+ replacement, sure.
Where does this myth come from? Looks it's about 10% battery degradation after 200K miles. Tesla is rating their batteries for 300K to 500K miles. Most American company ICE cars are scrapped by then. Not to mention all the ICE related maintenance costs over that time like oil changes, transmission fluid, timing belts, hoses, etc. etc. You can look at 6 to 10 year Model S cars.
