To be honest, I prefer to have a buddy over. I have lived with a repaired detached retina most of my life and about 5 years ago a torn one in the other eye. Both were fixed but bad floaters. Basically, my eyesight sucks. I need huge amounts of light to see stuff and it has really affected my confidence. When I walk I now find myself looking down non-stop. Some of that is due to cataract surgery with the near/far thing, but I like my car buddies and they are more knowledgeable than me. They also seem to have a lot more patience which helps me stay calmer also.
