There is nothing illegal about hitting a parked car. Period.
The law is broken if you attempt to avoid the responsibility.
But the fact remains, it is pretty embarrassing! And potentially costly.
I saw another reference to tort law, which is curious. Since the inception of no fault insurance, the tort regime has very little to do with auto insurance, and certainly nothing to do with a minor bump.
And I am not at all certain why:
1. The article was essentially an 'I have this friend...' story.
2. It was important that we know the driver to be an attractive blonde. What, can't unattractive people make mistakes, too?
If you really want to be 'steered right' - get advice from an Insurance Professional. Not the call center kind, go for the genuine article.
