Waveshare compare General Driver with ROS Driver?

[pitosalas]

You said that "this is a lower computer example for the UGV robots with ROS Driver: UGV Rover, UGV Beast, RaspRover, UGV02" and that the old version of UGV02 is driven by General Driver."

What is the exact difference between the ROS Driver and the General Driver? I can only find info about the general driver.
