Basta marunong ka din mag-coast at gumamit ng neutral sa A/T, it can save fuel compared to a heavy footed M/T. :D
There's really no need to shift back into neutral when you're coasting, as all modern A/Ts have DFCO (deceleration fuel cut off), effectively consuming no fuel when you're coasting (as compared to consuming the equivalent of what you'd consume in idle if you put the car in Neutral).
