@MontereyJack,
Quote:What was not true was "anyone". There are in fact other restrictions on who can park there. There are also one-time only restrictions on where you can park, which I could in fact use as real-world examples. And it's only once a month, and only for eight months of the year, so in fact there are a hedge of restrictions which do in fact constitute essentially one-time only conditions.
Now you've dropped it to "essentially". You are trying to create a smokescreen, Jack. You are being disingenuous. The fact of the matter is that your example describes the
general condition of 'could', one that exists for the past, the present and the future, [for this situation] subject of course to the conditions described by the particular statute or bylaw.
You [a person who meets the criteria of the law] could park in a particular place at any time as described in the law.
Quote:?Yesterday I could go to Disney World. (= unclear - did I go or not?)
Learners [ESL/EFLs] often say or write [that sentence, above,] with "could" when what they want to say requires "was able to". If they truly want to say that only the possibility existed, then a very careful paraphrase - or the addition of perfect aspect - is needed instead of the version with could:
Yesterday, the possibility existed for me to go to Disney World.
Yesterday, I could have gone to Disney World. [perfect aspect in red] (= implies I did not go)
Note that for expressing remote past ability - in contrast to immediate past - both forms are acceptable:
I was able to/I could speak German fluently when I was a child.

Quote:You are citing something as a general rule which no one who has ever used "can" and "could" has ever heard of and certainly doesn't follow. You are, in other words, being prescriptive.
Let's stay with the specifics, Jack.
Quote:All of which are irrelevant to the simple fact that "could" is being used as a past tense.
As you should be able to now see, Jack, 'could', in situations like your example,
are not being used as a past tense. You created an ungrammatical sentence and confused yourself into thinking it was grammatical by confusing it with the general condition, 'could'.
As was discussed in the opening pages to this thread, being a native speaker doesn't entail that one can accurately describe the workings of language.
Quote:That it can also sometimes be used to describe a present tense condition (as I did in fact note above) does not obviate the fact that it also describes past conditions ...
I never said that 'could' can't be used to
describe conditions in the past. But that use, in bold, is not the same thing as describing 'could' and other modals as having past [or present] tense.
Quote:that "can" cannot be used for.
I'm sorry to have to inform you that you are wrong again, Jack. 'can' can be used to describe the past. Even 'will' can be used to describe the past. Modals are emotive words, ie. we use them to state our emotions/feelings. Tense is indicated by other means, as I've described to you above with respect to 'could'.
