Well actually it's from the U.S., reported in the UK.
https://www.independent.co.uk/news/uk/home-news/bike-lane-cycling-road-safety-driver-deaths-fatalities-a8934841.html

"With added bike lanes, fatal crash rates dropped in Seattle (by 61 per
cent), San Francisco (by 49 per cent), Denver (by 40 per cent) and
Chicago (by 38 per cent)."

Cue the "Danger Danger" people to dispute the study. Maybe it wasn't the
bike lanes at all, maybe it was more people wearing helmets--wait that
couldn't be. Maybe it was more disc brakes. Maybe it was risk
compensation. Did gardening injuries go up or down?
