7 miles is the boundary of our knowledge

According to the Status Board of the DARPA Grand Challenge, Both the Read Team and the SciAutonics II team made it as far as 7 miles into the race. Two hours before the start, the total course length was finally given: 142 miles. This is a far cry from the original 250-300 miles given to the competitors a year ago. So the state of the art of our knowledge is now known: 7 miles out 142 miles. Out of fifteen teams, only four made it as far as five miles The remaining eleven did not make it past the second mile.
