Oh, so a fraction of a second later the surround view dissapears? What fraction are you suggesting?
That would depend on the speed of the car.
For example, if the front cameras can see one meter in front of the bumper, as the car rolls forward, what the car saw from that point forward would appear on the 360 view as moving toward the vehicle in a rate commensurate with the speed of the vehicle.
If the vehicle were to start from park, IE, no/old cached data, this area may be blurred or greyed out in some visually appealing way.
