I’d be interested if your theory turns out to be true.
Yep, from what we’re seeing/hearing, it seems to be shaping up to be a driver who feared for his life from armed mobs.
And that mob was armed, because as soon as the vehicle comes to a stop prior to reversing, at least 3 people can be seen immediately producing what appears to be baseball bats and clubs and started beating on the car..
In addition, the vehicle was being attacked by multiple objects being thrown at it prior to the incident.
