I’m guessing a lot of people don’t use them optimally. They used them how they originally used a ICE car. Unfortunately, that means they are lugging a large battery around for no significant reason.
I would also query how the hybrids are being designed however. There should still be a saving due to efficiency gains, since the engine can run at optimal RPM most of the time. The values scream that the manufacturers have over optimised for performance, rather than efficiency.
