This kind of accident happened in the first place because of panic. Many people have been cheated. When she panicked, people had no way out.

Secondly, because the doors and windows were blocked after the car fell into the river, there was no way to open them, or there was no way to open them consciously at the first time, so the chance of escape was lost.

Very few people are involved, probably because the window has been opened, so it is easier to escape.
