My mom has neuropathy from autoimmune diseases, pain was so bad she went to the Mayo Clinic and they stripped the nerves out of her legs. So she has no sensation either...dropped foot and all...her docs there have no issues with her driving, at least not yet which is good as she just got a Mercedes roadster.

Sounds like yet another very cool toy, John! Drive on! Nothing wrong with your driving when I was there, and I suppose nothing much has changed since then.
