text: Concluding with what i said at the beginning, the pictures we see are nothing more than a mesa. Science it to greatly advanced now and if there was any form of life on any other planets NASA would atleast have an idea of it. I don't believe this is an alien artifact, because Mars cannot support life.          I think driverless cars are a great idea. If you are a business man and you're busy and you need to get things ready on your way to work driverless cars could help you out, but you still need to pay attention to the road because the driverless cars need to be controlled under certain circumstances.
