Hi Ole_don:
___Welcome to GH!
1. As for ICE-Off ops, have you ever driven in an Insight when it Autostops? Similar dangers apply … So some of us will take it up to 75 miles per hour, not just 19 as the Insight is limited too

Vacuum assist does not disappear immediately as you have 3 to 5 uses normally. You will know when its time and/or you will have your hand on the E-Brake at low speeds. Steering at speed is not a problem imho. In the Insight, I actually pulled the Electric Assist fuse since it was way to light a feel anyway. I have a slight problem with the ¾ Ton 4x4’s at work in a FAS but I do not FAS those like the Accord and Ranger. Both of which are far more manageable.
2. You have made many assumptions and they are incorrect …
___AZCivic, any news?
___Good Luck
