This Unbelievable Empty Car Convoy Shows That Cars Don't Need Drivers Behind The Wheel

Looking to show off your car's fancy new smart driver assist features? Then just take the driver's out all together and let the cars drive themselves to form an empty car convoy.

That's what happens in this car ad from Hyundai where, after setting the cars on a nice long straight path, these stunt drivers switch on the "advanced smart cruise control" and bail out of the vehicles.

And, surprisingly the cars just keep on going—there's no pile up or cars veering off the road into a ditch. They even manage to do an auto emergency stop without it turning into a huge fireball. Impressive.

Check out the behind the scenes below to find out how they did it.
