Will an insured driver liability cover intentional damages to uninsured car that is parked?

Yes, as long as the car is parked on private property. Cars stored on private property and not "in service" are the same as any other property, If the insured runs into your parked car our your house the insurance will pay.

That's not quite correct. If the damage was intentional, meaning that the driver of the insured car deliberately struck the uninsured parked car, then the At Fault driver's insurance will NOT pay because of a clause in the policy that excludes coverage for 'intentional acts' like criminal activity (which is what this is). So the parked car's owner would have to pursue a civil case against the at fault driver and try to collect against their personal assets.
