I think it's hard to economically hit that and give a car that folks are OK driving within limitations.
Mazda tried to do a range extender setup on the MX-30, however it didn't sell that well and my understanding is the range extender wasn't good for hills or highway cases.
Non Range Extender setups, actually typically work better if you're stuck in gas mode than a range extender, mostly because you can use the mechanical energy from the ICE more directly than the losses of something feeding energy directly into the drivetrain. However, once you hit that point anything after 2 or 3 KWh of battery is just dead weight on the car. I'm guessing that's why even the Prius prime is only around 40 miles of range.
Of course, the elephant in the room is the US addiction to huge vehicles (which need even bigger batteries...)
Edit:
Seeing the edit of what I'm replying to, I'll add that yes PHEVs are probably a 'better' option than BEVs for many people, but the cost of a PHEV can be as much or more than a BEV. Look at a Chevrolet Equinox EV vs a Rav4 Prime. The Rav4 Prime is 10K more expensive. Happy to consider a different comparison here but overall nobody has figured out how to make a PHEV that is cheaper than a similar EV.
