At least that is how I look at it.
See, I have EXACTLY the opposite pov. A fully electric car (at this point in time) does not have the "range" that most people need in their lives. So, why buy a battery car that you have to plug in so you can go 30-40 miles when you can buy a hybrid that has a battery that has a longer range, and you don't have to worry about getting stuck on the side of the road, because if the battery runs out, you have a gas engine back-up. At least that is how I look at it.

You are much more right than wrong.I would love a small hybrid to buy.Exactly; you need an internal combustion engine to get any kind of range for your vehicle, and if you are going to have the electric part of the hybrid, then the I.C. engine part of the hybrid might as well be selected for efficiency without regard to drivability concerns which the electric part of the hybrid is so well suited to handle.
But only if it was a diesel/electric hybrid.

But there is a third, and even a fourth, option: compressed natural gas fuel with gasoline backup for extended (read, normal range capability.
The fourth option would be very expensive in capital cost, whereas probably the third option would be the most economical, when fuel cost and capital cost of the vehicle are all considered.
- It is obvious that natural gas is becoming the cheapest fuel, and its limitation is in the size/weight of the tankage to hold a sufficient mass (i.e., volume and pressure) of gas to give you good driving range. So the combination of a short-range CNG tank with a normal-range gasoline tank is undoubtedly the most economical solution for any vehicle which has room/carrying capacity for the CNG tank.
- That being so, the fourth option would be to go all the way on economy and el efficiency - a CNG-fueled diesel-electric automobile.
- diesel for maximum IC engine efficiency
- CNG for low cost per BTU, and for smoother combustion in a diesel engine (which must run lean enough not to pre-ignite until fired by an injected pilot charge of conventional diesel fuel oil)
- electric to control the speed (thus, the power output) of the diesel) and smoothly convert that power into torque at the vehicle axle, whatever the vehicles speed. And, perhaps, to store braking energy in a battery to be converted back to mechanical work when useful.
