If an uninsured driver backs into a parked car that was backed in making it less visible to the driver on private property and the driver nor it's passengers could see the car what happens?

You hit a parked vehicle. No matter how or where it was parked, you are responsible for the damages. If you hit the car, you could have seen the car if you had been looking. You have no insurance which is a violation of the law. Pay the owner of the car you hit and accept responsibility for your poor driving, and stop trying to blame this on how the vehicle you hit was parked. It is your fault plain and simple.
