I don't know anyone who'd readily admit that they're fans of public transport. They either use it because it makes more financial sense than to drive into the city or because they have no parking space (or it's too expensive to justify) for their own vehicle so they are left with no other financially sensible alternative. lol
From personal experience anyone who goes out of their way to say that they aren't 'fans' of PT are almost always wankers who think they're being subtle by implying they're too good/wealthy for it. lol
Ryan saying that he wasn't a fan was completely unnecessary in the context of the message he twitted. And his need to do that could stem from him not wanting to come across as public riding pleb to his rich buddies or some other lame social class insecurity he has going on.
