If you borrow a "demo car" from Tesla for a few days and then give it back to them, then yes they obviously have access to the logs.

Whether they have access to the logs of any random customer's car, I have no idea. But this doesn't prove things one way or the other.

They also pull the same stunt of selectively releasing info from data logs and spinning them to make the customer look like they're in the wrong every time a Tesla crash makes the news. There's a cell modem in every car to send them up to the mothership.

they log everything. even their home solar panels send usage back to the mothership with no way to disable
