Perhaps a plug-in hybrid in the role of daily driver car. Current plug-in hybrids get 40+ miles of pure electric driving which accounts for 99% of my driving days in that vehicle. They charge overnight using a standard 110V wall outlet. Thus, it would rarely need gas, and that's an attractive thought. That said, my wife and I have four cars - 2 daily drivers, 1 seven-passenger SUV, and one sports car, so we have some flexibility in selecting daily drivers.
