As a slightly side issue
My nephew (nearly 50) came a cropper yesterday on his bike
The council in their infinite wisdom decided to "upgrade" an existing cycle path in the centre of town (Newquay) the existing path was well used and well known and there had been no known issues as far as I know
They added a dividing kerb and then slanted blocks spaced every few metres , this is a shared road between cyclists on one side and buses/taxis/delivery vehicles on the main part of the road
Not realising the kerb was there he hit it and it threw him off causing scrapes and abrasions, it smashed his watch and damaged his bike, it could have been a whole lot worse
This is on a busy junction of three roads feeding into one, so you have to keep your eyes open for traffic
Why do councils do this? a complete waste of money, it must have cost thousands
