Robots on the open road. That could be the future for Nevada, which opened its roadways to driverless cars in 2011. Nevada also recently hosted the Consumer Electronic Show, where Toyota and Audi unvieled self-driving technology. So how far are we from the science-fiction fantasy of driverless cars? And how will it change how we drive in the future?

Having experience in many fields of science, I would observe that by far margin the very worst data sets I've ever worked with - those with all sorts of bizarre errors, omissions, etc. - are GPS data layers; and the errors are very often never corrected or ground-truthed. Roads that don't exist, roads that do but are vastly different than displayed, etc. are *extremely* common in this sort of data; and on top of that there are the inherent location errors of the technology, and even technology failures to contend with. So, considering what I've seen regarding both map databases and the reliability of electronic systems, I'd say that safe, effective driverless cars that depend on computerized maps or GPS are decades away.Tom Hurst –Jan 25, 2013 15:28:39 PM
