my mom is in her 70s and doesn’t know either. when she drives my car I have to repeatedly tell her what button to use to lower the driver window. She also just got an iphone after having a flip phone for decades. She has to be taught how to use it and often forgets it at home. It provides endless amount of amusement to see her 6 year old niece tutor her on how to use the iphone!
Sounds like me, never pumped my own gas and still have a flip phone. Works fine for me.
