That is certainly a factor. Crumple zones do a lot to absorb forces of impact and prevent intrusion into the passenger compartment. See also: [0]
We're getting to the point where a lot of cars that could be called "classic" still have the modern safety features without all of the connected bs. Most late 90s-early 2000s cars have multiple airbags, crumple zones, active seatbelts etc. without also needing to have subscriptions, telemetry, or really any connectedness at all.
Granted, subscription-based safety features aren't the point here, but they're certainly a future possibility (as discussed here last year with a motorcycle safety accessory[1]).
