1) PWPs are often the least reliable assessors of their symptoms and the extent to which they are impaired in carrying out a function 2) If your family won't ride in the car while you're driving, they are giving you a message 3) You may very well say "But I want to keep my independence." To that statement, I respond "Is the price of retaining your independence maiming or killing an innocent third party, to say nothing of your family and friends?" 4) I am confident that all responsible PWPs would answer no to point 3 above. I have been there. Stopped driving because of PD, was recertified in a rigorous testing program and now drive again.
