Sadly, the need to develop transportation options beyond the personal automobile is just now coming into the cross hairs of the policy makers. The movement is being stimulated, in part, by the notion that our aging society can't rely on just the automobile for its mobility. The problem is one of the more formidable challenges of the millennium. Solutions, of course, will come in time. Until then, your transportation options may be very limited.
Many families provide transportation for aging parents and relatives who no longer drive.
Work out a driving schedule and be flexible enough to allow for adjustments in plans. Call your aging family member ahead of time to confirm pick up time. This way they will be ready when you arrive. Calling can also save a trip if they decide not to go out that day. Arrange for prescriptions, newspapers, groceries, and so forth, to be delivered.
