We have been through this one already. There are 10 times the amount of regular drivers to cyclists, but the stats do not show that there are 10 times the amount of drivers being treated for head injuries. Most of these driver injuries recorded are also because they were't using seatbelts.
Another one of your pseudo-facts?
I would be interested to see the evidence for your seat belt / head injury link - but I won't hold my breath.
However despite this latest contortion to avoid the questions... let me point out (again) that in this case we are not talking about statistics, but a simple comparison between two unfortunates lying on two adjacent beds in an A/E department.
1. Two people are admitted to A and E
2. They have similarly serious head injuries
3. One is a cyclist
4. One is a Motorist
Q1. Does one hurt less than the other?
Q2. Is one less traumatic than the other?
Q3. Is the effect on the family less for one than the other?
