Cars from around 1998-2014 usually have side curtain airbags & adequate rollover durability. The only improvements since then that I'd even want at all are better EV batteries & marginal efficiency gains for IC engines, but those can be retrofitted &/or aren't worth the anti features they also added IMO.
If car companies want my business they'll have to remove the telemetry & automatic updates.
I don't care if I end up paying more to drive an old car eventually, but this approach has also been saving me money so far.
