Wow! does this ring a bell with me!  It's true, the "I'm the only one who can drive properly" seems to be a MALE thing. And also associated with recovery from OC.  I used to drive for a living, too - as a school bus driver in Chicago.  Once, on the way home from Rad Tx, all of a sudden my son shouted, Stop the Car!! Stop the Car!! We were in a residential area in a very narrow section of road - and not realizing what was wrong, I pulled over to the side.  Then I heard, "No, no!! not here, up ahead by the bushes!!  - where Paul opened the passenger side door, leaned over and the nausea took over, fertilizing the bushes.  I happened more than once, and for the life of me I don't know why the thought never occurred to me to have a throw up bucket in the car!! (a paper towel in the bucket helps in the clean up). I had everything else - Lots of water, lots of towels, tissues, etc. but no Throw-Up bucket!  Cancer takes away the control of so many things in a person's life, and for the Left brain male, being in control of something is important, so directing someone's driving becomes a small thing for the caregiver to allow him to have.  I would try to find other ways Paul could be in control, like giving him choices: "Do you want chicken broth or beef broth?"; "Want a big spoon or little spoon?"  "Do you want to take the expressway or the back roads to get to Rad Tx?", etc.
