Upon arriving to my grandson's daycare, I applied by brake and put my car in park and suddenly my car accelerated at a fast speed. My car moved forward across an area that the children are usually playing in, but because it was raining they were inside. Thank God! I can't even imagine what would have happened. My car finally stopped because I was trying to avoid the daycare's shed, but hit the corner of the shed and this stopped the car. The air bag did not deploy as well. I am thankful to be alive and unharmed, but most thankful that no one else was harmed. My husband took photos of the brake marks on the pavement and grass and of the vehicle after collision with the shed and showing it was in park.
