what's the use of "N" in a AT?

[crosswind]

Noob question guys.

What's the use of neutral sa AT and ano pinagkaiba nya sa Park?

Thanks

So it's not tiring to go from d to P in traffic situations
and you can save gas by putting in N during heavy traffic
and pagnagstall yung car(kung di minemaintain) lagay mo sa
N para maitulak o maitow/hihilahin paakyat sa truck
