>Why should they try to do that on snow/ice covered roads? Because, "Over 70 percent of the nation's roads are located in snowy regions, which receive more than five inches (or 13 cm) average snowfall annually. Nearly 70 percent of the U.S. population lives in these snowy regions." (http://www.ops.fhwa.dot.gov/weather/weather_events/snow_ice.htm http://www.ops.fhwa.dot.gov/weather/weather_events/snow_ice....) If they're able to nail down "the easy stuff" that's all well and good, but it sounds to me like most of the country is only going to benefit from the current technology indirectly (maybe a third of the supply chain will be automatically driven). But this "in a few years nobody will own a car because we'll just rent from fleets that will come right to your doorstep!" thing I hear a lot still feels like a pipedream to those of us who are currently prepping for 6 months below freezing. Who knows, maybe global warming will take care of this problem for us?
