While I can't comment on the exact instances of people using handicapped placards, I would like to bring up the existence of invisible disabilities [1]. These are disabilities that are not immediately obvious to onlookers. For example, people with xeroderma pigmentosum[2] have a very severe sensitivity to sunlight (sunburn within a few minutes, vastly increased risk of skin cancer). A handicap space would be needed to minimize time spent in the sun, but no issue would be present walking inside a building.
