text: This is the reason that i feel the way i do about giving machines freedom and trusting them to drive on the road with other people. I feel that the dangers far outway the risks for this idea and it will be much too expensive to try to adjust the roads to let independant machines drive around on them and endanger other innocent drivers on the road.-Going 'car-free' seems like an excellent idea!  Perhaps even less days of usage.  It would be safer and bring cleanliness to the air to whole new level.  No more angry citizens beacuse of global warming and our atmosphere will stop getting thinner.  As well as less deaths due to a motor vehicle.
