Driving me crazy

Hired a dual control car today and took eldest son for 2 hours driving around Edinburgh.His test is on the 8th jan so the clock is ticking.His driving was excellent and the dual control was not used (praise be!).
So it looks like another 17 year old is about to be let loose on the open highway, lock up your daughters, and check your no claims, and be afraid!!, be very afraid.
