Sounds like someone didn't understand how the parking assist actually worked in their car...

The incident occurred in the Target parking lot in Stuart, Fla. Jonathon Libratore, 27, told police he was attempting to park when the parking-assist function on his 2013 BMW malfunctioned, causing the vehicle to accelerate over the parking mound and collide with a parked car on the other side, according to the accident report.
BMW defended its driver-assistance equipment, saying it is designed to assist drivers with parallel parking and does not control the speed of the car.
The system does not control the speed of the vehicle at any time, BMW North America spokesman David Buchko told ABC News. The driver controls the speed of the vehicle with the accelerator and the brake.
