Re: What is a car?
Car data recorders have been a thing for more than 20 years, effectively anything with an odb port will have retained data in an accident that will be used in subsequent investigations.

Unless you want a pre 1999 non premium car without airbags, or abs then what ever you get will have telemetry.
Obviously, as you mentioned, newer cars have that constant upload capability, just that the feature you don’t want has been a thing for far longer than you realise
