This is why I'm over 40 but have only driven two cars in my life, excluding the one I drove from 16 to 17 before it broke down forever on the side of the road.
I know everything about my car. I can do anything without thinking about it. I know how fast I can be going around various sharpnesses of turn and remain fully in control. I know how to manipulate all the windows without looking. I know how to replace virtually any part that doesn't require special tools. I do all the maintenance, and I know how long to wait between servicing each thing. When I have to take it in for professional work, I can talk about anything regarding my car and the mechanics know they can't scare me with jargon.
I'm in the market for a new car right now, and that's what I'm going to miss: my car feeling like an extension of my body.
PS I fucking hate driving. Fire of a thousand suns. Please give me reliable public transportation. But until then, give me a car that my body thinks is a very heavy toenail
