I’m responding to “Seems like it's the new norm, like how radio became the norm in cars after some time. I bet people were complaining about that in the same way you are now.”
In 1975, there was no danger your radio would become obsolete or outdated at anywhere near the speed that an awful touchscreen tablet built into your car in 2020 will. So, I’m not referring to buying a car now with an AM/FM radio. I’m not sure what one would use that for other than as an AUX input.
