A few days ago I was driving north from Bagshot in Surrey. My destination in\nTT was in Carlisle. This is a trip I have made often and I was using my TT\nStart 25 simply to see how far I had to go and to see my estimated time of\narrival. I had driven up the M40 and was not far along the M6 on my way\nthrough Birmingham when I was instructed to turn of towards Sutton\nColdfield. I naturally ignored this but along the way I got other\ninstructions again to head for Sutton Coldfield. Again I paid not a blind\nbit of notice.\n\nI had the device programmed to take the "Fastest" route so the events I have\noutlined leave me puzzled. It reminded me of a situation which arose in\nFrance just after I had bought the device when I was headed along a road I\nknew well. On approaching a roundabout I was instructed to turn left. This\ncame as a surprise but I did so. After about 100 metres I was told again to\nturn left. This seemed absurd as I would have been going up a farm track.\nSo, I turned back and when I approached the roundabout the instruction was\nto turn left. I did so and was thus back on the road I had been on\ninitially.\n\nIt seems to me that one should perhaps carry a small bag of salt so that\npinches can be taken as and when required.\n\nAlaric.
