Well in your parking example, I think the better example would be, "not allowed to park here without a pass". You are allowed to park there, if you have the pass. If someone told me I wasn't allowed, I'd assume there was no way for me to park there. If someone told me I was allowed with requirements, then I know I can, if I can obtain the requirements. However I see your point of capable vs allowed, I just think it's a valid distinction to make. I'd never tell someone that they'd not be allowed to park somewhere, because that's not the complete picture. They might leave, thinking that there's no way for them to park there. That's not true at all, and I'd be in the wrong for misleading them, imo.
