Here's a nice article about a Tesla hitting 400K miles: https://www.teslarati.com/tesloop-tesla-model-s-400k-miles-battery-maintenance-cost/ Here's the relevant part: "Average battery degradation over the vehicle’s first 194,000 miles was around 6% with multiple Supercharger stops every day. Between 194,000 – 324,000 miles, the HV battery degradation was estimated at around 22%. According to Tesloop, this was likely due to the company’s practice of constantly charging eHawk to 95-100%, instead of Tesla’s recommended 90-95%". Note that they probably drive the car immediately after charging, so the theory "it is okay if you drive immediately after 100%" seems to be incorrect. I wish Clarity had the option to stop at 90%.
