Yesterday evening at approximately 7pm I entered a gated parking-lot with an attendant who inspected my vehicle, took my parking fee and gave me the required parking pass to park my vehicle. At approximately 11pm there was no attendant but there was an automatic gate that allowed the automobiles to exit. Upon attempting to exit the parking lot the automatic sliding gate opened and I began to exit. However, I had to yield do to the street traffic and upon stopping the gate slammed into the rear quarter panel of my vehicle 2 times simultaneously and was about to do it a 3rd time. As soon as traffic cleared I cleared the gated area and found my vehicle dented and badly scratched. My question is, does the lot have any liability in this case? I was technically not completely out of the lot and the damage happened due to what I believe to be a faulty automatic gate system.
