Basically true, but rather harsh? Compared to the detailed safety
assessment, it does rather stick out like a sore thumb for want of
supporting data. But the the +20% cycling / -10% driving indicates a
substantial increase in the number of active (i.e. several times a
week rather than weekend potterers) cyclists, and there is plenty of
evidence elsewhere that active cyclists live longer.
I think I could defend "result in gains in health from increased
physical activity" but I agree the "much, much greater" is not
supported by the report, particularly as (disappointingly) they make
no mention of severity of injuries.
