Back in May, I was hit by a car whilst cycling to work; I was on a roundabout aiming for the third exit (i.e. going 270 degrees around), (the car entered the roundabout from the opposite side of the roundabout to me (i.e. 180 degrees from my entry point). The car hit my rear wheel (destroying it) and I went flying through the air, hitting the road and kerb with my forehead. This caused bruising to the front of my brain and a further scan revealed a significant rotational injury. I came very close to death but miraculously came out of the coma and made a rapid recovery. I wasn't wearing a helmet at the time although one of the consultants in the hospital said that a helmet would have made no difference to the severity of my injuries. This has got me wondering if there exist any more robust cycle helmets than the styrofoam ones which may be able to reduce the impact to the brain should my head hit the ground at moderate speed (say 15 mph)? I have been considering a helmet camera and if I were to get one I would also like to get a helmet which does have some chance of being useful when it is needed.
