It was also about freedom. I couldn't wait for the day I didn't have to get my Mom to drive me everywhere.
Bicycles have existed for well over hundred years. Public transport is also a thing. I've had very little need for my parents to transport me since I was about 9 years old and didn't buy a car until I was 26, as did most of my friends.
My gosh you're right! Why would anyone want a car when those modes of transportation exist? It's a modern mystery!
