We drove. I sat on my mother’s lap in the driver’s seat and steered while she did the pedals, keeping us at 15 mph. She held her hands an inch away from the steering wheel, hovering, in case I overestimated one of the turns on our twisted road in Los Trencos, California. It was just the two of us, my mom and me — so nobody told her she was crazy. My mother knew: at five I was coordinated enough to steer the car.

In my aunt Mona Simpson’s book, A Regular Guy, a girl named Jane also drives. Her impoverished mother, Mary di Natali, sends her to find Jane’s rich father, Tom Owens.
