Nah, You all have got it wrong!
Put right arm out of window at all times, (it gets a nice tan that way). Use the left arm only for steering, lighting the fag, using the mobile, showing the V sign to all and sundry, tuning the radio. Oh and changing gear. If your left arm is busy with any of the forementioned tasks then use your right arm.
It is always nice to chat to other drivers on duel carriageways so be sure to keep all the windows open and ensure that you are doing either 100mph or 5 mph - never anything in between those speeds, (the police don't like that)
And lastly, make sure they enjoy themselves with a few pints of the Keo/Leon etc before driving,(it makes for a nice relaxed atmosphere in the car).
The only other pearl of wisdom I can think of is to drive on the pavement -it is probably safer!!!!!!!!!!!!!!!
I am out in September so see you there
