text: Google is one of the companies that want to get driverless cars out on the road to try and make the roads safer. But would that really make the roads safer or more dangerous? Google has tested driverless cars already and they stated,"Google cars aren't truly driverless; they still alert the driver to take over when pulling in and out of driveways or dealing with complicated traffic issues, such as navigating through roadwork or accidents." My question is how does the car know when to alert the driver? Does it have sensors on the front of the car that detect traffic, and if so what if the sensors fail and the car continues to drive at a steady speed right into heavy traffic before the driver has time to react because he was relying on a car to alert him? The same goes for the car detecting roadwork or if a person is crossing the street or someone riding their bike falls into the road. There are too things that could go wrong on these cars to have them out on the road.
