If you have to go to the doctor because of your injured foot and you drive a stick shift, do not give up meekly when trying to get either an extra driver or get somebody to allow you to borrow a car with an automatic transmission. If you go to the doctor with only your child who will be 14 the next day, the doctor might give you a nerve block shot in your left foot, preventing you from being able to feel it to the point where you're pretty much guessing on whether or not the clutch is even depressed, let alone fully engaged. You will get so frustrated that after you get off the major roads, and onto the back, country roads that you will allow your will-be-14-year-old-tomorrow to finish driving you home.
Note: We lived in North Dakota for a number of years, where the minimum driving age is 14 for a learners and 14.5 for a regular permit on "real" roads. The minimum driving age on farms is 12, and said child learned how to drive 2 years ago on a friend's farm.
