What happens to power steering/brakes etc. during EOC? Seems like that might not be the safest situation for maximum car control.

Your insurance would be completely void in an accident too, not worth the risk for a few cents of gas in my opinion.

Just a note. Hondas use a dual mode alternator to save fuel. During light loads and steady driving it charges at 12.2 volts to reduce engine load. When the lights come on or battery voltage gets too low it will switch to 14v charging mode.

Here's a good article about it.
