Personally, I think handicap spots and a lot of the laws around them are unethical. I even think it’s generally moral to violate laws that one has ethical or moral issues with following them. But even so, I don’t park in those spots because, even though I disagree with forcing private business to have handicap spots, the people that get hurt are the businesses and the handicapped, not the people who made the laws with which I disagree. But that’s not really here nor there with regard to the OP.
What bothers me with the OP is the idea that he is knowingly breaking the law, not for moral or ethical reasons, but for convience, and then getting upset that someone points out that he’s doing something illegal. Just because a cop doesn’t cite you for it doesn’t mean what you’re doing is not illegal. In my experience, it’s either because they don’t think it’s so bad, and thus you don’t really deserve the severity of the citation it would draw, like you’re obviously loading and there’s other spots available, or because it’s just not worth their time for such a minor infraction, like going 58 in a 55.
But the thing is, if you choose to violate a law, you should also realize the consequences that come with it. You will likely draw scorn from people for parking in a handicapped spot, they just usually won’t say anything. And you may not have gotten tickets in the past, but that doesn’t mean the next cop won’t give you one. And, sure, you’re carrying heavy equipment, but, like you said, you could have blocked the cars in and probably not gotten scorned. And if carrying the equipment that extra 10 feet is that impossible, then you probably should have specialized equipment to help you move the stuff anyway.
So, sure, the person you pointing it out is a little bit obnoxious, but you were knowingly in the wrong for a tiny convenience. You simply can’t defend that. If I get pulled over for doing 58 in a 55, saying that I never got pulled over for it before, or that it’s not so bad since everyone else is doing it, or that I was going to be a little late if I wasn’t speeding… none of those deny the fact that I was intentionally breaking the law. Either way, I don’t understand why you were so pissed and felt the need to write a pit thread. You got called out for doing something you admit you did.
