Every day on here, and on my own social media, I am shocked that soooo many people don't drive. My local FB group is constantly people asking for favours because they don't drive, they want a dump run, or someone to deliver second hand stuff to them. On here, the barriers to work, to childcare, to anything is so often that they don't drive!
For me growing up, learning to drive was just what you did. I don't have any friends who didn't learn to drive at 17. Most had cheap runarounds or borrowed parents car.
I totally understand it's expensive and costly to run a car but I don't think I realised how many people never learned!
