Dan is 100% correct - our first gen SRS is safer than a car with no airbags - for those ages 12 and up. There's no data (of course) on whether a 968 with an intact SRS would be more or less safe than one with a disabled system (or as in Waylander's case, one that came without an SRS from the factory). I would extrapolate that in most situations, the car with the disabled system would be less safe. It's very hard to say exactly how much less safe, however. In terms of relative risk, the best available study demonstrated that all cars, from all makers, with first gen units have a risk ratio of 0.90 compared with no airbag. So, based on that data, in 10% of crashes where there was a fatality, the fatality would have been prevented if the car had had first gen airbags. Again - it's hard to extrapolate to the 968 - but based on that data (and this is admittedly morbid, sorry) if one were to disable the SRS in 10 968s, and if there were fatal crashes in all 10, in one of those crashes a life would have been saved by having intact airbags.
Dan - to put your mind at rest - no Porsches were recalled for having Takata bags - every Ferrari manufactured from 2012 to 2017 was recalled, however.
At some point I might post my child seat solution. I'm convinced it's safer than the installed seats in at least three-fourths of the cars on the road. I have a 944 S2 interior in my car so the rear seats are a little different but I imagine it would still work the same.
I work at a Level 1 trauma hospital - hence the preoccupation.
