i got overtaken on the inside the other day, scared the shit out of me, i saw this car approching behind quite fast, put my indicator out and went to pull into the inside lane [dueller] as he came past at about 70, twas only a 50 limit aswell. nearly shit myself as i was literally just about to turn in and looked accross to check my n/s mirror as this xsara vtr came wooshing past.
living in cornwall - land with no m-ways - i've only drievn on them twice and found the whole experience quite frightening at first tbh, tis a ace idea though as you can overtake everyone at 80+ with out being held up by lorries overtaking other lorries and such like.
