Hi-jinks alone do not a documentary make, of course, so Car of the Future balances one-liner sarcasm, such as the ludicrousness of a 500+ horsepower Mustang, with somber narration delivered by John Lithgow, who points out that that the current number of cars on the road now would circle the Earth 1½ times, and that ratio is growing. That’s only a springboard, though. The show focuses more on alternatives than past mistakes. It’s interspersed with commentary from experts in various fields. David Greene, of Oak Ridge Laboratories, talks about the implications of the hydrocarbon footprint. Martin Eberhard demonstrates his Tesla prototype, an all-electric vehicle with a 250-mile range on a single charge, and capable of 0-60 in four seconds. Other experts, from diverse organizations ranging from environmental think tanks to General Motors, explore a multitude of options available as we wean ourselves from oil. They also delve into the problems those alternatives present.

In the end, Car of the Future poses more questions than answers. The future of the car is not uncertain—it’s only how it will change in a new environment. It’s an issue in which we all have a stake. To that end, PBS has a companion website to the show in which the public is invited to share their ideas about the automobile’s future.

There’s always going to be a place for Firebirds and MG’s. They’re just going to look a little different, and be a whole lot more efficient. We’ll all be driving Batmobiles someday.
