Blimey Rod, that must have scared you. For what it is worth this happened to someone I know, he was under a lot of stress and then one day ended up at the beach 100's of miles from work or home, he doesnt know how he got there or why...he drove all the way there though! It never happened again in over 12 years.
The speeds you drive at you might just have gone "back to the future", see if you have a receipt for a flux capacitor!
Now dont forget to finish my loom....I think I may have some of what you had as I cant remeber seeing my cossied 205 in over 4 months LOL
Keep Well
