Dr James Woodcock, a population health scientist from the MRC Epidemiology Unit at the University of Cambridge, said the health benefits could be even greater if cycling was made safer, as it is in the Netherlands.
"The Netherlands manages to achieve high levels of cycling with low risks, not by focusing on helmets and hi-vis, but by providing high quality infrastructure that physically protects cyclists from busy, fast moving traffic."
Amen to that.
