Why do you people like to drive cars with bells & whistles?

I don't understand it at all. I am 16 years old. I drive a 1973 Volkswagen Beetle. It has power nothing, no frills, no bells and whistles, just a body, an engine, a few seats, and four wheels. Why would I need anything else? I have about $12K in it ($4K initial, $8K stock and correct restoration to immaculate show condition). $12K can buy me a car with many frills, but I chose to have no frills (hell, I made the money myself). Why would I need power steering, or power brakes? Those two things are stupid and unnecessary. Why would I need a transmission that shifts itself? I can very well shift myself, and I heavily prefer to. Why would I need a nice sound system that would be distracting to my driving? Why would I need a/c? I have swivel windows. Why would I need a on that makes my window go up and down, or one that makes my seat do 50 different things? I can crank a window and I can push my seat back myself. Why do I need a DVD player that plays movies on my dashboard? That's why I have this thing called a TV. Why would I need hundreds of horsepower? I have 46 horsepower and it has more overall power than a Nissan Versa and a Scion xA (I've driven both, the Beetle has so much more low end power). What is the point of having any of those fancy doo da's? My main question- why do you "need" them?
