@EdithStourton wrote It had never occurred to me until a few years ago that some people didn't see memories of events like still images, or even movie clips in their heads (mine are a bit like old cine, they tend to get blurrier as time goes on). It boggled me, TBH, as I rely on mental images to navigate, for example - I couldn't necessarily tell you which exit you need off the multi-exited roundabout, but that it's the one just after you past the <mental image>.
I find navigating multi-exited roundabouts very difficult, especially when you have to change lanes at the appropriate time. Some say, it's the third turn or such, but that doesn't work, either. I could remember that it was the exit after the sign/turn/exit for The Bluestocking or somewhere, though.
This reminds me of many years ago, when I used to work on Saturdays but have a Thursday off, ideal for going to see cheap matinee performances in The Big City. I used to take my bike on the train, but I had a bad experience when I was tootling along in the left lane of three, next to the kerb, and suddenly went round a corner where 2 lanes of traffic joined from the left and found myself in the middle lane of a busy 5 lane roundabout. A mental image wouldn't have helped me then, but the online maps would as I would have avoided it.
