I wholeheartedly disagree. The car only knows how to do its job one way, and that's the way the engineers thought it out. Their way is by far not the only way.

And cycling the ignition is not a "distraction". Your eyes don't leave the road, you still have assisted steering, and the brakes are good for 4-5 touches. Seriously, of all the things that one can gripe on for being a distraction while driving, cycling the ignition is at the bottom of my list.

There is a time and place for DFCO usage but it has two severe limitations:

1) It steals momentum.
2) The engine uses fuel again once any of its conditions are no longer met.

Coasting with the engine off is much more efficient in all aspects when you know you'll be coming to a stop for a while, or when you want to maintain more momentum in between the times you let the engine run.
