We talk about ‘off-roading’ as the activity done by 4×4 vehicles and trail bikes that are capable of going off tarmacked roads. The tracks we’re concerned about aren’t roads as most people think of them. They are unsurfaced tracks, many of which would normally be covered in grass.  In most cases they have never been surfaced for motorised vehicles. OK, so they have legal status (most commonly as a ‘Byway Open to All Traffic’) but this is from the time when traffic was horse and cart!
