There is better data. According to TfL, in London (where RLJing is about 18%) RLJing accounts for about 2% of cyclist fatalities. Motor vehicles RLJing account for about 3% of cyclist fatalities and
TfL concluded cyclists not-RLJing accounted for quite a lot more cyclist fatalities.
Allowing cyclists to RLJ to improve their safety on the roads has been debated in the
House of Lords this year and
Paris has now made cyclist RLJing legal to cut the cyclist death and injury rates.
So lets cut all the bullshit about RLJing being dangerous/suicidal for cyclists.
