I drive an old automatic Subaru, haven't had any problems on the gravel roads. I just put it shift lock and keep it in second gear and keep those wheels spinning. I mean, most automatics have a sort of semi-auto mode that allow you to lock it in the gear of your choice. But obviously a manual has far more control.
