For those who are familiar with Raspberry Pi, For about $35-$40 you can can have a Pi Zero W act as a USB drive and it it auto-uploads any Saved Clips to an SMB share when you get in-range of your home wifi.
Instructions here:
marcone/teslausb - be sure to use the
one step setup instructions - it's pretty straight forward.
You just leave it plugged in your car's usb all the time and it will auto-upload any clips when you get home and then empty the Saved Clips folder so the drive doesn't fill up. I've been using this for a few weeks now and it works as advertised. Set-n-forget (at least so far)
