Green Flag

Just got an ad for Green Flag again. I an not currently a member but one thing tends to bother me. The photos on the leaflet are not UK based. (I have no idea why this irks me) A caravan with a bike rack? Is this not illegal in the UK. I certainly have never seen one. The motorhome in the same pic is LHD. The number plates are not visible so cannot tell for sure. Why not use local photos? There must be pleny available.
