Well, the fuel infrastructure already exists, and the weight of the ICE engine is at least partially offset by the smaller battery. I'm extremely skeptical of

  This assumes that a hybrid has to have a smaller battery to fit the ICE engine and/or that the ICE engine has equivalent weight/density. On the one hand, volume versus weight an ICE engine is generally "lighter" than if that equivalent space were tightly packed with battery cells. But on the other hand a car is not going to tightly pack the equivalent volume, most modern EV designs are a "skateboard" layout with all the batteries on the floor of the car. The front hood of the car is typically at that point unused space and many modern electrics place there now a "frunk" ("front trunk" or "froot"/"front boot" if you prefer Britishisms) for "bonus" cargo space. From that perspective, a hybrid has "free" space for a gas generator by taking "back" the frunk space, but they have to shrink the battery because of the added weight of the gas generator. (The skateboard has the physical space either way, it shrinks to keep the overall car weight below an aerodynamic threshold, not to yield space for the gas generator.)
