If you’re afraid to carefully drive a high quality and well maintained older car that was designed from the ground up with safety and quality at the absolute forefront- say an 80s Mercedes or Volvo, you would benefit from relaxing a bit and being willing to take slightly more risk in life.
Besides, I am not wholly convinced that improved safety tech is a replacement for the type of safety first engineering used in every tiny detail of those old cars, that mitigate certain types of accidents and injury that won’t be addressed in crash testing.
Back-up cameras are really important for kids who can't be seen in a rearview mirror. Those can be retrofit into an older car, but after having a kid I can see why these became mandatory.
