I think a power of attorney with more than one person named would be a good idea, now is time to set up whilst he is still able. Can totally understand why u are upset. As he is still able, he should be very involved in all decisions, only to be over ruled if he becomes unsafe. The transport is to him, a removal of his freedom, but he won't have quick enough reactions to drive at his age. Is there a local bus? He should get free transport. Are there any other safety issues? A family meeting with him there may be needed. Does he have a social worker? Could his home help come in even for an hour every day? Decisions need to be made now, while he can input. Certainly he sounds able with help to live where he wants.
