in a perfect world with good public transportation, how do you still accommodate both
A) You have excellent public transport suitable for service animals, wheelchairs, blind people, etc
B) People who can't take it for whatever reason travel by car. If you can get one (you won't get one for asthma...) a disability parking permit is a huge help. They're recognised globally and make it a lot easier to park in metropolitan areas. Those permits are valid whether you're driving or a passenger. With one of those permits even car-hostile places like the Netherlands become practical.
