Is the increasing popularity of fixed gear bikes sustainable?

MrSmith i think a fair few people try it get scared or just can't be arsed to get with the program with riding fixed as it's different to what they are used to, so they change back to ss/gears fairly quickly.
i think fixed will rise in popularity over the next 2 years then plateau out for another 2 then decline down to just above where it is now.unless there is a radical rethink of the transport policy in this country cycling in general will not reach government targets until policy changes motorists, town planners and big corporations attitude towards the bicycle. it's this attitude that stops cycling entering the mainstream and not just being the transport choice of weirdos.
i think i have strayed off topic there but it's sort of relevant.

it's peaked already! i don't see the fashionistas sticking with it for more than another year.

don't really care about the fashionistas though, fixed wheel bikes will always be around...
