This tool is meant to run directly on a vehicle-installed comma three, with
the openpilot/tmux processes stopped. It should also work on a separate PC with a USB-
attached comma panda. Vehicle ignition must be on. Recommend engine not be running when
making changes. Must turn ignition off and on again for any changes to take effect.
