I'm with Alphonso - metaphorically speaking. Certainly where possible, local governments should allocate some extra ashphalt to promote cycling. It might reduce the risk of cyclist/vehicle accident = $$$. But 'extra' lanes cost dollars as well and, as much as it hurts to say it, user fees would make sense. I just can't see how bike lanes can be considered a core service.
And Alphonso's on the mark with respect to manners on the road. Double file where possible, single where warranted - it just makes sense. I've been hit by a car - his fault all the way - it's not fun.
Play safe everyone
