Other than that, a $1 notepad and a pencil will do usage tracking just fine for years. You can't take a trip unless you're already sitting in the car where you can see and write down the info.
Gotcha - I guess I’m still not following though. Twitter and Reddit upped API fees because the data could be used to train LLMs.
Obviously if you had access to everyone’s driving/Tesla data - that’d be valuable - but I am assuming the API data is only for the owners using these the apps like you mentioned.
Is the data available across all users or are they prepping to release some kind of anonymized user data?
You can do basically everything you can do from teslas own app, but automated and even a little more. For example I use it to automatically control charging power to match the surplus of my solar panels, that keeps my grid-use for my car to 0kWh for roughly 5 months of the year. And I can set the charging power lower than I can in the Tesla app (app is 5A minimum, API goes to 0A), which is convenient for the solar charging.
And of course you can pull battery data, odometer etc. with it as well.
