Teslas have much smarter BMSs than you seem to be giving them credit for. For example, while supercharging, the car cools the battery actively and will slow the charge rate if the battery exceeds temperature tolerances. The car knows the temperature and state of charge (and probably more) about every cell in the pack. It's much more advanced than a hobby vehicle system. Same for storage under hot environments -- the car will protect the battery, even if that means using up some power to cool or heat the battery as-needed. (exception: Range Mode sacrifices battery longevity for maximum range and should be avoided unless completely necessary)
I'm giving the BMS plenty of credit. If it wasn't for the smarts in the system, our Tesla battery packs would die 10 times faster when we charge to 100%. It still doesn't mean it's a good idea to leave it charged for long periods and there is no flat rate .01% degradation by simply charging to 100%. It's far worse to leave it at 100% overnight than to charge to 100% and immediately drive off regardless of how good the management is.
