In normal traffic you shouldn't usualy require so much power that the ECU goes into open loop anyway (unless you live in germany and go fast).
However you do get into low load scenarios where your engine is inefficient a lot.
When in neutral with the ICE turned off, you could drive short distances entirely on electricity.

That is an order of magnitude more complicated, prone to failure, and expensive. As for the comment about engine load, I've seen 90-95% calculated load (before a transmission kick-down) when climbing hills on the interstate at 65 mph. 85% calculated load is not uncommon during normal acceleration.
