I share in these concerns.
Tesla collects information during crashes but will not ordinarily release any of it directly to the owner of the vehicle[1].
All modern Teslas passively use the cameras outside of the vehicle to monitor your driving to compare and improve their own self-driving algorithms, which is part of the reason the hardware is present whether or not you paid for the upgrade[2].
There's also the problem of forced updates, where some updates (particularly safety updates) must be installed, whether you want them or not[3]. In an extreme case, such as the aftermath of the Tesla battery that caught fire in China, they are believed to have solved the problem by limiting the maximum charge of the battery in software, reducing range significantly for a minority of drivers[4].
In all of these cases, user-control is sorely lacking.
