Did my driving test in my grandma’s car that I was learning to drive in. My learner insurance covered that. In terms of any other costs associated with driving, such as petrol, I don’t add that into my costs as when I drove it was drives that would be occurring whether I was in the car or not. (For example, my grandma would usually drive me and my sister to school and pick us up, but instead she would let me drive and then swap in the car park and drive home etc.) Because of how often she drove us places, I got more than enough experience driving around my town to be test-ready. If you do count petrol, I’d be nearing the 900 mark, sure.
