Do as the police do on the advance driving courses. When in your car, talk the journey, noting every road sign, bend and incline in the road, light and weather conditions, speed, gear changes etc. Talk clearly as if to someone in the car with you, but I suggest you do it when you're on your own, otherwise your nearest and dearest may summon the men in white coats. It's something I used to advise all my FI students to do and almost all found it useful.
