I've seen this commercial several times. GM SUV's with all wheel steering doing what farmers call 'crab steering' where both axles steer the same direction causing the vehicle to move laterally w/o turning. For what reason or advantage? GM tried this idea decades back and it FAILED.
I know why it can be advantageous with farm equipment but not with a vehicle.
