I’m no the one you directed that to, but…
First, what does “support the handicapped” actually mean? I mean, I sympathize with their struggles, believe they have the same rights and responsibilities as everyone else, and support government programs to help give them the opportunity to succeed or fail based on their talents just like the rest of us. I think requiring wheelchair ramps and handicapped parking is a good and just law. But I’m not like, I dunno, a fan of them or something.
Secondly, before anything else I want to stress that, as far as I know, I have never parked in a handicapped space.
A handicapped person is no more or less important than I am. Handicapped parking is a good thing, because its existence slightly increases inconvenience and frustration for most people while drastically decreasing it for a few, which is a trade-off I support… you might describe it as decreasing the standard deviation of suckiness in life. But the point is not that handicapped people are special and more deserving and due to their superiority they get the best parking spaces, the way a CEO might have a reserved space right next to the front door of a company, or the way season ticket holders might get specially good seats at a sporting event. The point is that setting aside particular parking spots for them has a huge positive impact for them, much more so than it would for anyone else.
So to me the issue is one of my convenience vs their convenience. In the vast majority of situations, whatever inconvenience I undergo by not parking in a handicapped space is trivial (oh no, I had to walk 5 minutes) compared to the inconvenience a handicapped person would undergo when there were no free spaces. That’s why I never park in handicapped spaces. However, if enough factors are in play, that ethical balance of inconvenience can change, with the three most obvious being (a) there are other free handicapped spaces, so it’s vastly less likely that a handicapped person will actually end up screwed, (b) my car will only be there for a short period of time, again greatly decreasing the chances of actual inconvenience to an actual handicapped person, and (c) for whatever reason the level of inconvenience to me is much higher than it normally would be, ie, I’m injured, I’m carrying a heavy delicate load, etc.
Now, I want to clarify two things. First of all, I keep using the word “convenience”, and I don’t want that to be misread as necessarily implying triviality. Handicapped spaces are there to make life easier for handicapped people, not to make life fundamentally possible. Handicapped people survived without them, but they make their quality of life better (barring extreme situations such as parking at the hospital when there’s a life threatening illness). So the thing to balance in the ethical scales here is not life and death but convenience and quality of life.
Secondly, I have absolutely no problem with the law as written, despite the fact that I think there are times when it’s ethically reasonable to break the law. This is for two reasons: (1) there’s really no way to properly codify the exceptions that couldn’t be abused, and (2) the penalty of paying a hefty fine acts as a deterrent, hopefully keeping people from getting complacent and abusing the system.
Hypothetical question: you have a magical orb that can see into the future and magically predict with 100% inerrancy whether a given handicapped spot will be needed/desired by an actual handicapped person in the next 5 minutes… so you’re driving around needing to park for 5 minutes, looking for a spot, and this orb beeps “clear” or “not clear” as you drive past handicapped spots. Would having this orb beep “clear” make you more likely to be willing to park in a handicapped spot during exigent circumstances?
Other hypothetical question: there’s a venue with a limited amount of parking in its official lot, and if you can’t park in its official lot, you literally can’t go there and all and have to turn around and leave (ie, it’s right off a freeway off ramp, no side streets at all, nowhere you can park your car and walk). You go there, and literally every single non-handicapped space is full, but several handicapped spaces are available. It’s very unlikely that any non-handicapped spaces will free up, because there’s a concert, so everyone is arriving at the same time, and will leave at the same time later. Is it ethical for you to park in a handicapped spot?
