i recall the moment my car accident happened : when i arrived the pharmacy parking lot, absolutely i slowed down my car and approaching the parking space. when my car 's front tires touch one side of the pavement ( there are 2 pavements separated apart about 3 feet with soil where are planted with flowers, each pavement is approximately 1/2 foot thick and 1/2 foot high ). while i stepped on my car's break pedal, i felt the car suddenly lost control and it jumped on my side's pavement, and almost at the same time, both air bags burst, made the car ran over to almost a half of the distance between 2 pavements ( about more than 2 feet ) and hitting the rear of another parking car ( on opposite side of my car's parking space ( lot ). therefore : 2 reasons, the breaking system didn't function well at first, when the car jumped to the pavement, the air bags suddenly burst, made the car madly jump over to another side of parking space ( opposite side ) and made the accident serious ( 1 car's rear almost was crashed, another car's rear on the other side of parking space was touched by this car' s head almost no evidence ). finally, my car stopped, can't move anymore !
