You can configure a Raspberry Pi Zero W or Raspberry Pi 4 so that your Tesla thinks it’s a USB drive and will write dashcam footage to it. Since it’s a computer:
Scripts running on the Pi can automatically copy the clips to an archive server when you get home.
The Pi can hold both dashcam clips and music files.
The Pi can automatically repair filesystem corruption produced by the Tesla’s current failure to properly dismount the USB drives before cutting power to the USB ports.
