text: These driverless cars are a hazard. even though they could be helpful in the future. In some way they seem to undertested amd people don't want to trust them. Manly because you would still have to pay attention to the road, still have to drive through construction and wrecks, and are technically still not fully legalised in some states like California, Nevada and Florida. With a bit more field testing these driverless cars could be one of our greatest achivements. But they won't be totally ready until 2020.       What is that thing on Mars?
