Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Not my opinion, the doctor's. Yeah, he should have been looking but then the driver should have checked his fuel gauge before he set out on his journey and then he wouldn't have run out of diesel. I've been riding for over 25 years and I've come of at slowish speeds whilst climbing in the ice more than once and my head has hit the ground. I don't know what would have happened had I not been wearing a lid.

The doctors opinion is no more valid than yours, it is pure guess work.

A parked car is a parked car, don't see the relevance of blaming the driver or why the car was parked where it was.

And yes you don't know what would have happened if you had not been wearing a helmet, i.e. could have made no difference - which is why this debate goes on.
