I am with lucky on this one yea i agree it is dangerous out there there is no denying that but!
they need a kick in the behind even when they are in ample cycle lanes they manage some how not to stay in them and try over take each other like the frickin racing in the tour de france.
granted if you want to pass someone do but what happens is they rarely signal and when they do its a signal and gone not signal look and progress if its safe madness in the highest order
