I'm a middle aged woman who's had a driving licence since I was 18yo. I drive short journeys most days and a journey of 120 mikes round trip most weeks and would say I'm an experienced, competent and confident driver.
However for longer trips, which tended to be as a family, I always let late DH drive. No real reason other than he enjoyed driving and I am lazy was happy to nap on journeys. I would take a shift on very long journeys.
Since he died, obviously, I have to do it all myself. I took DS2 for a uni tour yesterday, 3.5 hours each way. DH would have done it without thinking. I was really struggling and stopped for a rest every hour on the way back.
