I had an incredible blast on the A1 between Berwick and Edinburgh a couple of months ago. I was in the Porsche, moseying along without a care, and saw another car popping others in the mirror. This went on for a while until he was behind me. He was obviously up for it and the road was splitting into dual carriageway about a mile ahead. There was a trundler in front of me so I just moved right-sideways so racer-boy couldn't see past to overtake before the DC. As soon as the road split, trundler stayed left and I floored it. Full down, expecting this bloke to vanish backwards, but he stayed glued to me like I was towing him. Right on my bumper. I could see that it was a BMW from the lights and grille but no idea what the motor was and this bloke obviously knew the road better than I did (or had misplaced faith in me!)
We were using both lanes through several curves and on one straight he tried to pass but didn't have enough before a right bend and had to tuck in behind me. Then there was this biiiiiiiig fucking left and I couldn't see the other end of it so I backed off. We were doing about 130 into it and there was a straight with another right ahead but I'd backed-off too much into the left, was out of gear, and didn't want to drop it on the flaps and cart-wheel off into the heather. He completely did me, and came past at around 30mph so was likely doing 150-160 (this was when I saw it was a 20 plate M3).
He was a very experienced driver, to be fair.
And then the whole motorway stood up and applauded.
