i do not cycle in sheffield any more as i got sick of cycle ways,most of which are pavements or a bit of painted tarmac,both of which or in constant renewal,this means that cyclists are having to go in and out of road traffic or "annoy" pedestrians.i can understand as a car driver that having to give room time and again to a cyclist in narrow lanes on same route slows us down,roadworks are also seemingly endless.as for cyclists not obeying red lights i agree however they only put themselves at risk,in general,what about the next three to four cars that go through!not to mention mobiles
