My only unofficial lesson was in a friend's SWB V8 Land Rover that he bought to do up after getting rid of the Vauxhall Cavalier that he got as his first car. I tried out a long dead-end road on an industrial estate. The torque scared the hell out of me, never having driven anything, so I turned down any of further goes for fear of wrecking it.
I didn't start learning properly until my late 20s and had a false start with an RAC instructor in a Fiesta (guy made me nervous of scuffing the wheels).
After a couple of months pause I signed up to the driving school who were on that series about hopeless learners. The instructor I got was a lovely guy, patient and easy to chat too. He had a Mk2 Clio 1.9td and was a keen believer in safe driving but still having fun with whatever torque/power you had.
I always booked two hours lessons and he would say pick a direction and we would drive an hour that way and then head back a different route. He would maker turn thr car around in stupidly narrow places, hill start in the snow on dark winter evenings and anything else he could think of that provided 'real' driving challenges.
I was still learning when my son was born and diagnosed with a severely disabling condition. He would let me fit my lesson start and finishes around when I needed to get stuff to the hospital or just so I could finish get there after work.
I failed my first test because on the way back to test centre I was asked about what I would be doing after. It took mind of my driving and the tester failed me for undue hesitation waiting to pull out onto a roundabout.
I passed second time a couple of weeks later and two months after my son was born. I got to drive him home about ten months later.
