After Swerving Into a Lane Full of Traffic, a Nightmare Unfolds

The girls were in a hurry...

After jumping across two lanes, a real nightmare unfolds.

The girl in the video is jumping across two lanes at once, and it is soon obvious that there is a reason you are not supposed to do that.
The video appears to be from a rear facing camera, of a probably larger vehicle since it did not even budge when the girls smashed into it. The impact was strong enough to cause the airbags to deploy, yet in all that smoke confusion the female driver gets out of the vehicle with the phone in her hand.
The only logical explanation is that she had it in her hand upon impact, which would imply that she was using is while driving, and is probably the reason of the crash.
They could have at least shown some concern about the state of the other driver.
