This type of discussion scares me.
Occasionally I do realize I drove pass where I needed to get off, but normally do not get lost and such. BUT, I keep losing my car. It's so aggravating. I can't remember where I parked it! I used to specifically pick a landmark to remember, now I forget to do that. Twice today I walked out of a store and had no idea where I parked. Thankfully, both times, my car was visible, so I found it right away. I can't imagnine having to give up driving.
