text: It stated that " For starters they needed a whole lot of sensors." So, they needed sensors to recognize where they are at. They use these sensors for everything. It's all computrized. What if the computer stops working? This just basically means that these sensors are liable to stop working. These sensors are liabile to catch on fire. Last but not least what if you have a horrible person running the computers, and instead of sensing someone to where they needed to go he/she sensored them to a dark alley. The driver would be in trouble and theres nothing no one could do about it because their would be no proof. You guys are putting your lives at great risk!
