They offer you a new way to ride a four wheeled vehicle in open spaces ( the contact with nature cannot be more direct ).
They offer you a great match between the exciting sensations you get riding a motobike and the steadiness of a four wheeled vehicle.
They give you the chance to create a strong link with nature, but also with the vehicle itself, calling forth the desire of using them again...Just for this reason it would be worth trying them.
It is an alternative way of driving even though they have rules that differ from the motobikes and off-roads ones.
