krousdb]I do it because it is a waste of fuel not to do it.
I don't find turning a key very much work. Nor do I find engaging the clutch much work. I would have had to do it anyway, even if the engine was on.
Im picturing someone driving down the interstate or in city traffic doing this, wouldn't your steering , braking & accessories be compromised that would be a safety issue wouldn't it?
My wife drives it now instead of the Outback. 45MPG vs 18MPG. She only burns 40% of what she used to.
I can relate to this as we got rid of our 2nd-3rd car and have the prius & a pick-up that now only gets driven on sat. as Im stuck in a lease or I would have gotten another hybrid...
My point is that you don't need to a hybrid to get good mileage. You just need to be willing to put in a little extra time and effort. I got a sporty two seater with removeable top for one fifth the cost of another Prius. The mileage isn't quite as good as I would get with the Prius but I am still learning to drive the del Sol. Targeting 60 MPG by spring.
You may not need a hybrid to get good mileage, but it seems your going through more wear and tear on the car that was not designed for that kinda use but more power to you.. 
BTW, I don't fight the ICE. We work as a team.
