So the husband is going along at a slow rate of speed as his wife is checking for said turn-off point on said booklet/map. That is what it looks like to me.
Being a solo rider I would have to stop & check it out myself & then make said turn-off as I understood.
Nothing wrong if husband & wife are going along at a leasure pace even slower then max speed limit. She looks comfortable with the pillion riding position & bet you they have been doing this for a number of years & she can probably feel the pitch of the bike if he banks a bit to the left or right & rolls right along with him.
A true husband & wife two-some with identical helmets, identical jackets, trousers to probably boots & gloves. There are such people you know. Probably the only thing not being two-some is the one bike & she probably does NOT like the idea of riding a m/c other then being a pillion rider.
We have chaps on this & other m/c boards of where the wife does not ride the bike, but likes to ride pillion.
