Remember that "planned obsolescence" is a term from the 1950s, when automakers were deliberately using shoddy components in parts of the cars (radio components, switches, etc) so that they could save some money then when the part failed outside warranty, the owner either paid for a replacement or bought another car.
I think of things like that when people complain that "they don't make them like they used to".
maybe we can't do the exact same design as the 60s, but take all the tech out of new cars. Take all that time/money/effort and focus on the efficiency and reliability of the car, as a car. Lighter, cheaper, longer lasting, easier to design, less recalls and TSBs, less hacking, higher Consumer Report scores.
Were people actually ASKING for cameras and and pop up shifters and 10 warning bells and 6 zone climate control and 4 touch screens in their new car? People would still buy just as many new cars if none of the tech was there.
I search out used cars that are light in tech. No need for any of it.
