This reminds me of walking around NYC near ground zero about a month after 9/11. There were a ton of cars covered in dust and people hard written stuff like “we will never forget” on them.
To me it seems especially grim because the owner was well enough to drive themselves to the hospital, park and get themselves inside and were never well enough to leave (except in a bodybag or maybe a hospital transport to a hospice).
Or maybe they were a career criminal who was driving this stolen car and parked it at the hospital. Then they got into another stolen car with a bunch of guns in the trunk. And then they killed a bunch of other people!
