How does the poet cope with her emotions during the drive?

During the drive in My Mother at Sixty-six, the poet copes with her emotions by attempting to distract herself from the sadness she feels about her mother’s frailty. As she looks out of the car window, she focuses on the “young trees sprinting” past, which symbolize the vitality of life and help shift her attention away from the painful reality of her mother’s aging. Despite her inner turmoil, the poet tries to maintain composure, keeping her emotions in check as she bids her mother goodbye. This moment of distraction reflects her struggle to balance love and sorrow while confronting the inevitable passage of time.
