Well, that's one factor

According to investigators, there was nothing in place to stop the truck in garage accident that killed a woman who was eight months' pregnant. I'm assuming they mean there was no kerb or other barrier between the parking space and the wall. One interesting twist, apparently the truck was a newer model Ford F-150, so it has an on-board data recorder that will help investigators figure out what happened. The driver did not appear impaired but submitted to blood tests for alcohol and drugs, and is said to be devastated by the accident, which is quite understandable.
