Steeplechasing, cycle-style

Anyone using the cycle routes in Swindon will be accustomed to the sort of obstacle in the photograph. They’re usually at the junction between a cycle route and a road, presumably to stop children riding straight onto the road without looking. A child on a bicycle could, just, negotiate their way around the zig-zag of barriers. For an adult the only way is to push their bicycle through or, where there is open space (as there is for most examples in north Swindon), ride round the outside, thereby making the whole thing totally pointless. The example here is one I came across today on Whitehill Way in Freshbrook, at the highly dangerous junction of… one cycle path with another cycle path. Apart from the possibility that whoever was responsible for this would like to start a new type of steeplechasing event using bicycles, just what is the point?
