It's like watching a ballerina dance. It's like seeing an invisible hold never let go. It's a multi-axis laser cutter with such pinpoint accuracy that it never moves from the spot it's set at. It's impossible. If these are our future robot overlords, it makes complete sense. Take me now.
Right now your GPS sucks in cities but, soon, that will change. Scientists have developed a new system that increases its accuracy by up to 90%—it can tell where your vehicle is within an amazingly low margin of error of just three to six feet. Right now, the error margin in urban driving can be more than 160 feet.
