I had a serious accident 5 years ago (not my fault). I had to carry on driving because I was visiting my mother in hospital so I just got straight back on the horse. Then the pandemic came and I didn't drive much.
Then, this summer, I booked our holiday in the UK. DH (who is a competent driver, aged 74, but doesn't enjoy it) said I had to do all the driving. It certainly boosted my confidence afterwards to think that I had covered a huge distance all on unfamiliar roads, driving on the other side of the road, negotiating sheep on the Moors, through big towns like Manchester, coping with potholes and narrow parking places driving an automatic, which I am not used to, and with him navigating! Because we were travelling relatively short distances every day, there was, unfortunately, little motorway driving involved, but I even coped with the smaller roads.
I just took each mile as it came, and didn't think of the challenge as a whole. As with most problems, it is always easier when broken down into its individual parts.
