The casualty rate is 5604 per billion passenger miles cycling, and 238 per billion passenger miles in a car.
The death rate is 30.9 per billion passenger miles by cycle, and 1.9 per billion passenger miles in a car.
As noted, cyclists have a similar (only slightly lower) risk of casualty to motorcyclists, but much lower risk of death - slightly lower than a pedestrian. This presumably reflects speeds, etc., and does suggest analogies with motorcyclists are not wise.
In terms of 'serious injury' these are about 1/5 of the total for cyclists, i.e. 1120 per billion miles
To put it another way, if you did 52 * 50 mile weekly rides for 20 years with 12 people, that would be 624,000 passenger miles cumulatively, and you would expect to see a SI in that time
Just checking the figures, assuming the 1120 is correct, 1000,0000,000 /1120 = 892,857 passenger miles per SI. Assuming serious head injury to be 40% of injuries, once in 2.232 million miles cycled. Is this near to what would be expected from the data?
