I had a motorway lesson a week after I passed my driving test, I recommend it to anyone that is learning to drive.You can buy post test lessons which include Mororway tuition etc. Good idea unless the instructor is a hogger.
My instructor rocked up in the 1 litre micra and then asked me to help him take the L-plates, signs and roof box off the car to put into the boot prior to the lesson. I asked if this was because it was illegal to have L-plates etc on the motorway and he replied that it was because they typically blew off at anything over 60mph
