Yep. IMHO, the driver was too gentle in trying to leave. If unknown armed individuals surrounding my vehicle, I would consider any action to get out self defense. I would not have done the "gentle" back up, move forward, back up, etc. rather quick deliberate actions. It look like other cars had blocked a easy path in reverse, and the best bet would be to back up a bit, then find the clearest path forward and take it not letting off the gas or stopping until you are clear.
