Someone Loses Control Parking and Hits Two Other Cars

This video blew up over the weekend.  It's surveillance cam of a fancy car trying to park on a driveway with an incline.  But it suddenly lurches forward

and hits the car in front of it, and then veers off the incline and smashes into a car parked on the street.  Some people are blaming it on the driver's confusion over how to use the "electronic parking brake."
