The owner of this bicycle was obviously not willing to wait around for the local council to plant more shady trees and create safe dedicated bicycle lanes and has instead come up with a possible low-cost solution.
As for the danger of cycling along our streets …. maybe we should all hope that more and more cars will clog up our roads thus forcing them to drive at a snail’s pace. Then it might be safer to cycle breezily past those crawling vehicles without having to worry about being hit by a speeding car or lorry. (But mind those death-defying motorcyclists weaving past the cars!)
