Isn't it more efficient coasting in gear/engine on?
From what I understand, Almost all modern car engines shut off the injectors when the engine is down revving, foot off the gas in gear.
Sure, I won't coast as far a the proponents on here who coast in neutral, engine off...which is very dangerous, and in most jurisdictions, very illegal.
Even coasting in neutral with the engine idling will waste more gas than engine even braking, as is see it.
Thoughts?
