artilce 3. can be justified (之后 for location relations) cause 之 is a ancient depiction of a foot. So 之后 can be "treated" as "position after someones foot"

@Silvia It seems to me that that switching 停 and 车 would also create an imperative: 停车在外面。

some off topic: I'm a native speaker. I think the 2nd sentence "车停在外面。" means "The car is parked outside.". If you want to express "Park the car outside.", as an imperative sentence, I think it should be "把车停在外面。".

1. `之后` means `after that (something said earlier)` which requires a context as the reference point of time. `以后` can be used with or without context. When standalone, `以后` means `from now on`, `in future`.
2. In general, `之后` refers to a shorter time period than `以后`. The difference is akin to that between `after` vs. `since` but weaker. In imperative sentences you may want to use `以后`.
3. `之后` can also mean `geographically behind` though this usage is not common. `以后` cannot be used in that way. Example: 围墙之后是一排小树。
4. In colloquial language they are pretty much interchangeable. People don't pay much attention to the differences in #1 and #2. In other word, `之后` can also be used without a context and means `from now on`, etc. In writing and formal speech, however, they should be used with precision.
