Has anyone considered how he managed to drive about 600 miles and didn't fill up with petrol?
Regarding testing of eyesight, many years ago I collected my first pair of varifocals. I hadn't used glasses before and was very nervous of driving. The glasses were obviously OK for driving but I wasn't. I got my husband to drive me around some country lanes, housing estates and a dual carriageway so I could sit in the car and watch the road as a driver without actually driving. He also took my out at night for the same reason. I didn't drive until I was confident in my corrected vision.
