| In the United States,focusing on Massachusetts.Most major grocery chains,use mostly plastic shopping carts.It seems that this new technology might see through a metal warehouse,but these plastic, shopping carts,go be used once,people,outside in the parking lot.Also,alot gps signals are built into raoads, or cell phone communication could easily be monitored.Also American cars are not made so much with steel metal,but lighter metal,like aluminium and these radar detection device might be viewing you as your driving.Don`t worry,drink some decaff. |
