Also, I have a suggestion regarding the vision thing. I find it easier to pay attention to my surroundings when I have some repetitive work to do with my hands. I like knitting, but of course there are lots of other things you could do.

When I first learned to knit, I had to stare at it, but once my hands learned what to do I could look around and notice more things. I think it helps me not to focus too much on any one thing. When I’ve been doing too much reading, my mind starts to go too fast and I have trouble concentrating. Knitting helps to slow my mind down to a normal pace.

I think doing handwork might help you to replicate the results you get when driving, because it’s a similar mental process. Once you learn to do it, it requires part of your concentration but not all of it. Anyway, it’s just a suggestion, perhaps it will be of use to you, and perhaps not.
