A few days ago I was driving north from Bagshot in Surrey. My destination in TT was in Carlisle. This is a trip I have made often and I was using my TT Start 25 simply to see how far I had to go and to see my estimated time of arrival. I had driven up the M40 and was not far along the M6 on my way through Birmingham when I was instructed to turn of towards Sutton Coldfield. I naturally ignored this but along the way I got other instructions again to head for Sutton Coldfield. Again I paid not a blind bit of notice. I had the device programmed to take the "Fastest" route so the events I have outlined leave me puzzled. It reminded me of a situation which arose in France just after I had bought the device when I was headed along a road I knew well. On approaching a roundabout I was instructed to turn left. This came as a surprise but I did so. After about 100 metres I was told again to turn left. This seemed absurd as I would have been going up a farm track. So, I turned back and when I approached the roundabout the instruction was to turn left. I did so and was thus back on the road I had been on initially. It seems to me that one should perhaps carry a small bag of salt so that pinches can be taken as and when required. Alaric.
