No, good hybrid drivetrains charge the battery during normal driving not just breaking. It saves gas by avoiding the least efficient RPM ranges of the engine.
~80%(battery & conversion losses) of 35% fuel efficiency easily beats 100% of 10% fuel efficiency. Using a 200HP engine to creep around a flat parking lot or run the AC while waiting etc is simply inherently inefficient so they turn the engine off. As a bonus you get that quick EV acceleration without an oversized engine that’s rarely operating efficiently.
As to emissions from car manufacturing, don’t ignore emissions from gasoline manufacturing. People get these comparisons wildly wrong by only looking at tailpipe emissions and ignoring upstream extraction, refining, and transportation emissions over the 25+ lifetime of an average car.
