Mr Barr said at that stage he desperately searched for a way to stop the car, and noticed the gearstick in drive mode.
He reached between the front seats and jammed it forwards to park mode.
“Things are fuzzy but I kept my hand on there,” he said.
“Nothing would have moved my arm, no way.”
With the car not able to accelerate and with injured victims trapped under the wheels, Doyle’s rampage was over.
As the vehicle came to a stop other people shattered the windows and tried to drag Doyle out, which they succeeded in doing after Mr Barr reached forward and released the driver’s seatbelt.
Detectives viewing dashcam footage from within Doyle’s vehicle have said they believe Doyle may not have been aware of Mr Barr’s presence in the car.
The labourer said he is unsure.
“I find it a very interesting question,” he said.
“He was repeating the same thing over and over, ‘why won’t they move out my way?’
“Was he asking me? Was that a statement? I don’t know.”
