The Delphi Automotive driverless car has successfully completed a cross-country drive from San Francisco to New York with very little help from the humans aboard. It apparently needed a hand on certain roads without proper marking and on some highway ramps. Nonetheless, it is being hailed as a success. The CBC report embedded here contains interesting information about the computer’s tendency to do some of the defensive things done by drivers. Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions.
