It is 2016 and technology has definitly advanced since the first car was built but, are driverless cars really nessicary? Google cofounder Sergey Brin envisons a future with driverless cars, smart cars that can drive themselves. Driverless cars could be convnient but, there are and always will have too many safety risks, all the technology envolved will be too expensive and it is unnessicary. People have been driving themselves around safely and without a problem for ages now so, why change that? Google has had driverless cars since 2009, that have driven more than a half million miles without a crash but so far, they aren't truly driverless. Google's driverless cars still alert the driver to take over when pulling in and out of driveways or dealing with traffic issues like, driving through roadwork or accidents. Technology is always unpredictable which can make it dangerous. For example, something can go wrong with a sensor and the driver may not know. The car can get into an accident potentally putting the driver's life at risk. Most driving laws focus on keeping drivers and passengers safe. And lawmakers know that safety is best achieved with an alert driver. I don't think putting a person's life at risk is really worth the small convnience of having a driverless car. Developing a safe driveless car will need alot of technology with will be so expensive. In the late 1950s, General Motors created a concept car that could run safely on a special track. The track was embeddded with an electrical cable that sent radio signals to receviers in the front of the car. Engineers at Berkelely also tried a concept similar usind magnets with alternating polarity. These smart-road systems worked well, but will require huge upgrades to existing road, which is something to expensive to be practical. I think driverless cars are simply unesiscary. People have been driving cars around themselves for years. In a situation where somebody cannot drive themselves around they can ask somebody else or ride in a taxi cab. Having an actual human behind the wheel will always be safer than depending on technology. I am aganist driverless cars because the technology invovled will be too expensive, there are and always will be too many safety risks and they are simply unesiscary.
