Which method use higher fuel?

[supmet]

A better question is when the hummer coming behind you isn't paying attention because they are on their phone and eating a big mac, which method will allow you to step on the gas and get out of the way the fastest. Well, maybe my scenario doesn't work in singapore, but the point is in neutral, park, or with the car off, you can't move quickly in an emergency situation, and you're saving 20 dollars tops if you keep the car 10 years.
