I had what looked like a 100 year old woman driving a 20 year old metro pull out infront of me on the A4 about 100 yeards infront of me while i was doing 50, its a good thing that the other lane was empty otherwise their would have been trouble. IMHO old people are without a doubt the most dangerous drivers on the road. A 17 year old 2 times over the drink drive limit has reactions faster than a sober 70 year old.
