Just keep in mind:
* if you scratch the car on the bushes on the side of the road, it's your fault, you didn't listen to her.
* if you bump the rearview mirror on oncoming traffic, it's your fault because you didn't listen to the car's assist even if you bought that that she didn't thought was good value for money and better spent on a weekend away.
* if nothing happens, it's still your fault because she is the boss and she says so!
It's a no-win situation... Wifes are lucky that we love them so much...
