Funnily enough at least in my personal anecdotic case it works about like that. I do just remember when my meetings will be (or look up where the meeting was decided on), do try to remember what I had planned (sometimes I forget, but almost always for the better), and written notes are rare enough that pen and paper are sufficient. And also don't have a driver license. I don't think my case is exactly rare, even among softdev croud.
