I dunno how you evaluate whether one is an enthusiast any more but I very much doubt it'd be 'mostly enthusiasts'.Not everyone would have been doing the rides poll either, so I think that evens it out. Not everyone will have done any of those things.
In fact, I’d guess that it would mostly have been enthusiasts doing the ride poll.
Either way these internal surveys are complete junk as they are all biased so as to ensure a specific result.
