A Raspberry Pi Zero W, Raspberry Pi Zero 2 W or Raspberry Pi 4 can emulate a USB drive, so can act as a drive for your Tesla to write dashcam footage to. Because the Raspberry Pi has full access to the emulated drive, it can:

• automatically copy the recordings to an archive server when you get home
• hold both dashcam recordings and music files
• automatically repair filesystem corruption produced by the Tesla's current failure to properly dismount the USB drives before cutting power to the USB ports
• serve up a web UI to view or download the recordings
• retain more than one hour of RecentClips (assuming large enough storage)

This video (not mine) has a nice overview of teslausb and how to install it:

If you are interested in having more detailed information about how TeslaUsb works, have a look into the wiki.

• You park in range of your wireless network.
• Your wireless network is configured with WPA2 PSK access.

Required:

• Raspberry Pi Zero W (Adafruit or Amazon)
  or Raspberry Pi Zero 2 W (Adafruit or Amazon)
  or Raspberry Pi 4 (Adafruit or Amazon)
  Note: Of the many varieties of Raspberry Pi available only the Raspberry Pi Zero W, Zero 2 W, and 4 will work with TeslaUSB.

• A Micro SD card, at least 64 GB in size, and an adapter (if necessary) to connect the card to your computer.

• A mechanism to connect the Pi to the Tesla: a USB A/Micro B cable for the Pi Zero W, or a USB A/Micro C cable for Pi 4

Optional:

• A case for the Pi Zero. The "Official" case: Adafruit or Amazon. There are many others to choose from.
• A cooler for the Pi 4. The Raspberry Pi 4 uses much more power than the Pi Zero W, and as a result can get quite hot. The "armor case" (available with or without fans) appears to do a good job of protecting the Pi while keeping it cool.
• USB Splitter if you don't want to lose a front USB port. The Onvian Splitter has been reported working by multiple people on reddit.

To install teslausb, please use the prebuilt image and one step setup instructions.
