This appears to be untrue. High-mileage Teslas are showing about 10% range degradation after ~250kms on the odometer: https://electrek.co/2020/06/06/tesla-battery-degradation-rep...
Notably, this isn't about Tesla specifically — the broader point is that the technology exists for mass-market car batteries to support many hundreds of thousands of miles/kms within a reasonable lifespan of the battery.
How is this not real? This is literally something I can observe myself. I bought a new Model 3 LR AWD in 2019, and when I look for used listings for the same model right now, the exact same models from 2019 with about 22-30k mileage on them cost as much as what I paid for the new one 2 years ago.
Sure, you might say it didn't appreciate since it costs just as much. But imo, when a used car with solid mileage 2 years later costs as much as the new one with zero mileage did 2 years ago, I would definitely count it as, at least, "doesn't depreciate in value nearly as much as cars are expected to".
But, re "there is so much misinformation about Tesla it is unreal" — I agree, but that doesn't mean you can just categorically ignore _all_ information about Tesla.
