Wrong.
The woman has a permanent parking placard which must be renewed annually.
Believe it or not, people, including permanently handicapped do have more than one vehicle, or may have to operate a vehicle, not their own.
Illinois Secretary of State
How do I obtain a disability parking placard or disability license plates?
An applicant must complete a Persons with Disabilities Certification for Parking Placard/License Plates form (VSD 62) certifying the disability by a licensed physician. If the applicant has a permanent disability, the form must be mailed to the Secretary of State's office (by either the physician or the applicant). Based on the information on the certification form, a disability parking placard and/or disability license plates will be issued.
If the applicant has a temporary disability, he/she may take the form to a Secretary of State facility and receive a temporary disability parking placard, which is good for up to six months, depending on the disability.
Virginia’s laws are similar. My wife’s disabilities are permanent (she was born with them) and thus has a permanent placard.
I’d be willing to bet that she was driving her own car.
