Automatic trannies in these cars use the shifter as advice only. If shifted into neutral at speed, the engine would spin out, which is very damaging..
It doesn't seem you know much about cars. First of all, "spin out" isn't an automotive term. And 2nd, what do you mean by "spin out"? Modern cars have a rpm limiter which limits the RPM of the engine to some preset RPM limit. Have you ever driving a manual and hit the RPM limiter? It'll cut power to the engine. Same thing with neutral. An engine will not be damaged if you gas it in neutral, even to the RPM limit.
