Hi again:
Sorry, but that's the way you made it sound, i.e. "would it count as a claim" - of course it would. These insurance companies aren't daft, that's just a fact.
Anyway, has she considered reporting what happened to the Police? Because from what you say, it would amount to what is known as a "fail to stop road traffic collision", and there is just a chance that the culprit could be traced, albeit a long shot, worth a try.
Plus, she can also get a reference number to pass on to her insurance company.
