Best of both worlds, in my opinion. You never have to plug your car into a charger and you can always rely on the gas tank to get you where you are going.
I do, too. IC engines used by themselves have to be sized to meet the highest demand the driver will place on them. Hill-climbing, acceleration into rush-hour traffic for example. The rest of the time the engine is loafing along at 15%, but the friction and pumping losses are still there. Efficiency sucks. A much smaller engine working at, say, 75% of capacity will do just fine if the driver can call on a supplementary electric boost for the short time that additional torque is needed. This is somewhat comparable to the current practice of installing a small engine with turbosupercharging to create peak torque when demanded, but turbos have their own drawbacks which, as an early adopter in the '80s, I know much too much about. I won't have a turbo today. I learned my lesson. A hybrid, yes, if I could afford one and it didn't require an associate's degree in computer science to drive it.
