Driving to the eye clinic, no Full Self Driving (FSD) after an incomplete over-the-air, navigation update. Parked an hour and a half later, FSD visualization came back and I was able to turn FSD back on. Next on deck, regressive testing of navigate. So half a day of whackiness that will soon be forgotten. BRW, leaving the eye clinic with diolated eyes makes you really appreciate Autopilot and FSD. Good news! At age 73, I have age related cataracts but treatment is not needed at this time. I bought the Tesla to compensate for age associated physical changes. Bob Wilson
