Done properly a passenger wouldn't even notice.

That being said, most of the top hypermilers on here have the strategy of "all or nothing". Meaning that their default driving mode is EOC. They only use the motor to stay within a predetermined speed range. No matter how long the coast will be, they pulse at a determined engine load and then EOC once a certain speed is reached. This is repeated over and over as long as traffic and condition allow. So really the goal is to only use the engine to give yourself a boost. While the engine is running, it is always running at the most efficient load.
I couldnt have said it better myself really!
I do tend to slightly disagree with the clutch wear issue though.
I have replaced clutch slave 1x already and the neutral pedal switch.
this could be attributed to normal wear but its not normal unless your stuck in bumper to bumper traffic to engage a clutch and disengage it every 40 to 160 seconds. Nor does a throw out bearing enjoy its extra duty cycles.
Lets get it straight foremost these are wear componants and each cycle is wear.
Will I stop doing it probbably never the maintenance will come and I will roll again. Most cars wont see all or most of these issues before the transmission synchros go out or other failures happen, and this is why we dont put cars back together with worn wear componants anyhow. As said most here will experiance some failure at some point because these are wear componants but Ive got 45k miles on the POS KIA and basically doubled the F/E with $75 bucks in clutch parts, It is a non issue but it will happen not just murpheys law here its fact.
