Im not completely sure i understand your question tbh but ill have a stab at answering anyway, i take it you mean somewhere you can take your relative yourself so you can give the relative extra experience on the road without having to pay this �20 per hour......... When i was learning to drive my Granny used to take me to the nearest industrial estate later on in the day after we knew nobody would be about but still light enough for me to see what i was doing, we would then go through the basic motions... reversing round corners, parking and so... this was fine enough for me to begin with then we went on to letting me go a little further, drive us to the nearest town then onto driving home..... back then you only had to do a compulsory 7 lessons with a qualified instructor before you could sit your test, not sure what it is now though. I dont see why busier roads and towns are out of the question as long as the relative holds there provisional licence, is fully insured on their own policy or on another family members policy and has sufficent enough knowledge of the highway code and manouveres etc...
Hope i helped a little.... and good luck!! :)))) x
