This is apparently (i.e., unverified) footage of her car careening down the street moments before the crash.
Are the brakes of her car making that screeching sound??
If the video really shows her car, I see several things.
First, the car goes by at an enormous speed for a residential area and she is constantly braking the car, but the brakes do not have brake pads, the sound is that of the iron support where the pad goes, rubbing against the discs.
In my job I sometimes have to drive fast and the brakes wear out a lot, so on two or three occasions I leave the car without pads and the iron support, when rubbing against the brake discs, makes that noise.
In short, she had no brake and was pushing the pedal hard trying to brake.
On the other hand, being the country that she is from, it is almost certain that the car has an automatic transmission. The car speeds by without slowing down at all, which should happen by simply letting go of the throttle.
The brakes could be due to poor maintenance of the vehicle, but the fact that the car does not slow down implies a "failure" of the car at the control unit or software level.
If the car in the video, it's hers, it's highly suspicious.
