I tell my friends about what it's like to go to places and have to leave because there's no accessible parking available. They listen intently but sometimes it isn't until they go somewhere with me and actually experience seeing an illegal parker that they get how frustrating it is to see cars without proper tags taking up the spots. It can mean missed appointments and changed plans. Because of it's frequency I sometimes have to bring an extra driver along who can let me out and park the van. It often seems as if these laws aren't being enforced at all.
