Car batteries are not much like phone batteries. A car battery pack is a system in itself, with thousands of small cells supported by cooling, heating, monitoring and balancing systems. edit: there are recommendations for Tesla daily use that say go to 90% most of the time. But still a bit different to putting 12% completely out of reach like Audi have done.

Well actually, by default Teslas charge daily to only 90%, to preserve the battery. You can however change it to 100%, if going on a trip, or otherwise needing the full range.

  There's no reason to believe 100% is actually 100%.

Tesla is also deep in the red so I partially read these PR announcements with a grain of salt as they desperately try to acquire capital

  Exactly. Financials come out today, and after saying that it's "profits from here on out" ntwo quarters ago, Tesla will probably produce another huge loss. As is par for the course, their PR news will come hot and heavy: Cars go further! Our entire business model is now robot taxis! None of it matters if you can't sell your product at a profit.

    To be fair to Tesla, the "profits from here on out" statements came with some caveats around Q1 2019. I get the feeling that they have moved even more one time charges into the one-time-bad-really-bad quarter as a result. To be fair to your point, the "Autonomy Day" presentation implied a willingness to renege on the promises about other quarters as well.

  Toyota's debt to equity ratio is three times that of Tesla's.

    With 5x equity and decades long stable business, you can carry a high debt load. Tesla has more risk of a stock price plummet if they falter.

Apparently the max charge percentage is user configurable, see https://teslamotorsclub.com/tmc/threads/set-charge-limit.131301/ https://teslamotorsclub.com/tmc/threads/set-charge-limit.131...

  Yep it's just a slider in the UI and app. I generally leave it set to 80% and then 100% for big trips.
