Yep, just seen that. My bet is that you only have minimum cover when actually on a greenlane, even if you have a fully comp policy. I think they use greenlaning as a marketing ploy but actually offer exactly the same cover as other insurance companies (apart from Swiftcover).
I used to use Adrian Flux too. LV were a lot cheaper - they don't specifically offer cover for greenlaning but don't have daft exclusions either.
