Why the fuck would you want a parking lot at a hospital? Imagine surrounding a place where every second matters and where tons of people have physical disabilities with a massive field of useless metallic obstacles that everyone has to move around and can get murdered by. Can you imagine someone who needs to be driven having to walk all the way across a parking lot because the spots closer by are all full. Can you imagine being blind or old or anything else that makes you unsuitable for driving but perfectly capable of taking public transit and having to ask someone for help and cross a fucking parking lot to get medical care?

Or... Imagine instead if the default way of going to a hospital was to take the subway, with a level boarding station right beneath the hospital with elevators that can take you immediately to the right department. And in the rare cases that someone needs to be driven to a hospital, the taxi or ambulance doesn't need to dodge the hundreds of people who were perfectly capable of walking or the giant metal boxes they leave behind.
