Once they figure out the technology, maybe. Hybrids are slightly more fuel-efficient than normal gas-engined cars, but only slightly. It would take years (and years.... and years) to save enough on fuel to cover the extra cost of the vehicle. And then, when you finally did that... you'd have to pay a few grand to replace the battery (which only lasts a few years).
The technology just isn't there yet. Right now, the cars are too expensive, and just not good enough to warrant the extra cost. If you're on the fuel-economy bug, buy a diesel. You'll save thousands of dollars up front, and end up getting better gas mileage than a hybrid.
As I said, they're pointless.
