I see someone has pitched in early with a 'road tax' suggestion
Yes, what would he suggest we pay i wonder? How about a hundred pounds a year to cycle over potholes, glass and round their parked cars! They just don't understand! I cycle on a busy road that's falling to pieces, i have to weave in and out to avoid the holes and there's a kind of a tram line where they've patched the thing up. If you get your narrow road tyres caught in this tram line you are likely to wobble, even come of your bike.
I drove over this road yesterday, and as a motorist i have to say that my large/wide tyres made it a comfy ride where i hardly noticed the problems i'd have to endure when i cycle on that road! I also noticed that it's probably my half a ton in weight car that's caused the potholes, not my 22 pound(in weight)road bike!
