Well I do understand science, because I am a scientist, a specialist in cardio respiratory health. Hence I support anything that reduces asthma in children, especially children from poorer homes living on polluted roads in London. Rosamund is against LTNs for this exact reason https://londonnewsonline.co.uk/mother-of-a-nine-year-old-ella-who-died-from-fatal-asthma-attack-hopes-inquest-will-save-future-lives/. Her daughter died of asthma and she lived on a polluted road. Anyway .... Back to cycling - I think in London separate cycle lanes are the only scheme that will make me feel really safe. There are just too many bad car drivers out there. Do you remember in the first lockdown, less cars, but people were speeding and there was some terrible driving. Sometimes even when just walking the driving scares me, when I cycle I?m scared all the time!
