This essay is part of a series on not owning a car.

The weekend before Halloween, my car-less family got a loaner plug-in hybrid-electric car to try. You see, the City of Seattle and some other local public agencies are testing the conversion of some existing hybrids to plug-ins to accelerate the spread of these near-zero-emissions vehicles. As a favor and, perhaps, for some publicity (this post), the city's program manager offered me four days' use of the prototype -- previously driven by actor Rob Lowe.
Enthusiasm about plug-in hybrids -- like their now-almost-mainstream siblings the gas-electric hybrids -- has been running high of late. For example, the California Air Resources Board is among the toughest air quality regulators in the world. When members of the board's expert panel reviewed the evidence on plug-in hybrids, they issued a boosterish report predicting widespread adoption and fast market penetration. The Western Governors' Association is similarly smitten (MS Word doc). The tone of some popular press reports makes it seem that the vehicular second coming may be at hand.
For this auto (pictured in our back yard, with our Flexcar visible out front), I wondered, would my family give up its car-less ways? Would the joy of these 100+ mpg wheels cause us to end our 21 months of car-free-ness, emulate Rob, and buy our own plug-in?
The short answer? No. Plug-in hybrid-electric cars hold great promise, as long as we can fix the laws. And the technology. Oh, and the price.
None of those fixes are "gimmes." Without fixing the laws -- and specifically, without a legal cap on greenhouse gases -- plug-ins could actually do more harm than good. And without the second two fixes -- working technology and competitive prices -- plug-ins won't spread beyond the Hollywood set. (Echoes of this point are in Elizabeth Kolbert's latest article in The New Yorker.)
But I'm getting ahead of myself. Let me start at the beginning.
