If you're so sick you can't drive, and you don't have a partner with you, wouldn't you be in a similar position if living in a house? Is throwing up in a bucket

If you're so sick you can't drive, and you don't have a partner with you, wouldn't you be in a similar position if living in a house? Is throwing up in a bucket that difficult? How often in your life are you "too weak to even drive", and how often does that situation arrive without days notice so you can get near help? If I come down sick, I typically get 24-48 hours warning. And in decades, I've never been truly bedridden or unable to drive. Why can't you leave your vehicle when sick? What's the fear of discovery? "This guy is really sick and needs our help. But wait, he was secretly sleeping in a stealth van - let him die!" You strike me as particularly risk averse!
