London's new cycling czar today set out ambitious plans to cut a quarter of all car journeys in London.
Walking and Cycling Commissioner Will Norman wants to persuade motorists who make 'unnecessary' journeys to become cyclists or pedestrians or switch to public transport.
Mr Norman, a former Nike executive, targetted short car rides including shopping trips and the school run.
He was hired by London mayor Sadiq Khan to replace previous cycling supremo, Andrew Gilligan.
City Hall claimed the NHS could save £1.7bn over 25 years if every Londoner walked or cycled for 20 minutes a day.
Mr Khan has promised to spend £154m on bike lanes and other measures to promote cycling.
Mr Norman believes changes to road layout could help reduce conflict between cyclists, pedestrians and motorists.
