Is this a age difference occurence?

My wife claims she hates the way I drive and chooses to drive. Which at first kind of bugged me, but after a while I saw that whenever I did drive, she was a nervous wreck. She's a pretty bad passenger and a pretty bad copilot ("Come on babe, left or right?!"... She freaks out, I go straight, she gets mad that I didn't give her enough of a heads up, I laugh, etc.) which I caught wind of pretty quickly.

So, I weighed out my options...

1) I drive and have a wife that is completely stressed out and not very pleasant to be around (although I love her to death even when she's not pleasant to be around haha)

2) She drives, I sit in the passenger seat, help copilot and relax. I have my moments of being a crappy passenger, but that's only when my wife passes a perfectly good curbside spot because she's afraid to parallel park (hate hate hate).

I guess I could be considered part of the "younger crowd" on this site (I'm 31), and I guess it could be a generational thing. My brothers and I were taught by our Old Man to always drive when with a girl, but that logic seems to be shifting with the years that pass.

Does it make me less of a man? Hell no. Because at the end of the day, my wife's happy, I'm happy, which usually means my chances of getting laid are higher than those guys who choose to be stubborn and drive their pissed off wives around all day lol
You forgot choice number 3. Separate vehicles, or I drive period. But I'm but one opinion here.
