Besides the public relations value - hence the celebrities and politicians - GM will also be gathering feedback on how people use the vehicles, how easy they find fueling them, and how they like driving them day-to-day.
Over a 30-month span, vehicles will be lent for 3-month periods to various households in the New York City, Los Angeles and Washington D.C. areas.
What those families will find is an experience that, except for fueling with pressurized gas and an awkward bump in the cargo space, is very much like driving a nice crossover SUV. But this one has water vapor for exhaust and zero engine noise.
