This is an insane video but it has a happy ending.
A couple was outside of a 7-11 in Daytona Beach, next to their Dodge Charger. Then a carjacker walks up and hops in the drivers seat.
There was a child in the backseat so the mom jumped into the passenger window while the dad jumped into the drivers side window and began punching the suspect, according to ClickOrlando.
They managed to keep the suspect from driving away although the car rolled forward and crashed in the parking lot. The father punched the guy and held him until police arrived.
