a) Off-road cycle paths are statistically more dangerous than roads.
b) Off-road cycle paths often take you on a circuitous route, forcing you to go miles out of your way, or cross loads of extra sets of traffic lights, all of which are against you.
c) Off-road cycle paths are nearly always at a lower priority than the roads they cross.
There is a cycle path parallel to the road at the end of my cul-de-sac. This road has many other cul-de-sacs branching off it. If you choose to cycle on the road, you have right of way all the way down the road. The only major danger is from people overtaking and turning left at the same time; this generally isn’t too much of a problem if you cycle defensively.
However, if you cycle down the cycle track, you have to give way at every side turning (approx. every 50m). To do this, you have to give way to traffic coming out of the cul-de-sac, and traffic coming both ways down the main road - you have to look 3 ways at once. As a result, you have to slow down to a virtual stop every 50m or so. This is a real PITA.
To cap it off, the end of the path is funneled into a 30m-long bit of pavement with iron railings down both sides; the separation between the railings is about 6" more than the width of the handlebars of my bike. If I go slightly off-course, the handlebar gets caught, the bike veers into the barrier, and I come off - possibly over the barrier into moving traffic. Coupled with that, it’s also a very busy pedestrian junction, with people approaching from 5 different directions. If I follow the Highway Code’s recommendations and use the cycle “facility”, but mis-judge who is going where, and hold someone up, then who’s fault is it? “Bloody cyclist, cycling on the pavement…”
I also recently had a “discussion” with an idiot who insisted on walking his small yappy dogs down a designated cycle path, without a lead. Every time I got near, his dogs would try to run under my wheels. When I asked him to put his dogs on a lead, he said that I “shouldn’t be cycling there”. When I pointed out the fact that it was a cycle path (and I was actually standing on a painted cycle symbol), he said that he “didn’t believe in them”.
Coupled with this are the beliefs that:
a) Just building cycle paths and forcing cyclists onto them perpetuates the myth that cycling is inherently dangerous, and that you can only use the road safely if you’re in a car
b) Building cycle paths and forcing cyclists to use them erodes the rights for cyclists to use the road in the first place, since motorists expect cyclists to just “get off the road”.
Just because a cycle path is there, doesn’t mean it’s actually useful or safe. In many cases, it’s neither.
