ya want daft cycle lanes?? brighton is the capital..
http://www.weirdcyclelanes.co.uk/ if those dont work..
i stick to the roads unless there is a cycle path built into the road on the left - if its part of a path theres no point for me, when moving at 25mph (realistic, on the flat, because my sprint to work takes under 10 mins.. ) - some kiddie steps out in front of me (its happened) i've no chance of stopping, he could realistically be killed (not an exageration - the head cannot cope with decellaration of that level). bikes are silent and cars are not, which makes this a lot more likely to happen.
as for cycling 2 abrest - if the road is very narrow (not really enough room to overtake) i'll happily do this as it stops cars pulling stupid overtaking manouvers - they can overtake when there is no traffic coming the other way - i've no vendetta, this is just common sence (i'll also cycle a bit further out if i see fit, when riding by myself on a narrow road).
i tend to cycle alot in buslanes, as they're normally bus-and-cycle, and if not i can keep up with the busses anyways.
as for road tax, there is no such thing. i believe you're talking about a 'vehical licence' which licences you to own a vehical which is used or kept on the public road.
i do think all cyclists should be encouraged to drive, and visa versa. i'm a very swift cyclist, and love cutting through stationary traffic in the city centre - but i've definately become a more considerate rider since starting to drive, and i'm a more considerate driver because i ride.
a bike 'licence' (cycling proficiency test anyone??) is a good idea, but i dont think it'll happen whilst the government are trying hard to encourage people to ride.
