I think all those sensors turn into big data. There's an enormous amount of information streaming off all those cameras, rangefinders, gps, accelerometers, and stock on-board car sensors (like traction control). Add hard realtime constraints for computing solutions, and you've got to handle a giant pile of unavoidable data to ensure safety. Of course, I'm sure the data's culled a thousand ways to Sunday to make it manageable, but it's going to be like a self-contained industrial process, which can generate positively stupid amounts of data.
