The inertia reel did its job at 230 KPH.

OzOne, head on over to Dave at AutoAvia and suggest same. you will receive a lecture about the lack of effectiveness of retracting seatbelts compared to correctly fitted fixed belts. The stretch in the retraction mechanism causes more movement on the body and greater injuries.

Occupant safety in cars is largely a compromise between protection and convenience. Laws could be passed where all vehicles had to be fitted with Nascar style roll cages and everyone riding in them had to wear a full face helmet and a 5 point harness. Doing so would effect a *massive* reduction in the road toll, but at the same time make your average driving experience about as enjoyable as a trip to the dentist. Instead we settle for the maximum amount of safety that we can have *without* being inconvenienced to any great degree. Personally, I'd like to see a return to the days where wearing seat belts wasn't compulsory. Not because I don't think they're an effective safety tool, as I do, and I also think their use should be compulsory for children 16 and under. I just think the choice to wear one or not should be left up to the individual adult. -- Regards, Noddy.

If by much "more in control" you mean you were held into your seat better then IMO a better way to fix that is to fit better seats, most car seats don't have a lot of side bolsters to prevent you moving side to side, seats like Recaro's and some seats fitted to better sports do and they do hold you in place a lot better especially when cornering quicker than normal.
