Honda Civic Hybrid Battery

Richter, unlike the Prius, the Civic hybrid only uses the electric motor to assist the gas engine when more power is demanded. Is it possible your light foot has gotten heavier over the years? On a 100-mile trip, your electricity usage should vary based on the type of driving. If the trip is mostly highway driving, there should be very little battery usage since you would cruse at a constant speed. In stop and go traffic, or in hill country, you would drain the IMA battery faster. Is it possible you were kinder to the accelerator in the beginning?
