Imagine: it's 2050, and all around are cars buzzing and swishing through the streets, quickly roundng corners with expert presicion. Then, upon closer look, one can see that every single car has come without a steering column; they're self-driving. This idea may seem far-off, even alien now, but could very much be a realty. Companies like Google have had independently drivng cars since 2009. But before we can introduce waves of driverless cars to the road and every day life, the most important aspect has to first be perfected: safety. A driverless car has the capability to replace a manual vehicle as the safest cars on the road. But to acheive that, manufacturers need to break down laws that have been set since automobiles have set wheel on the roads. Most states it is illegal to operate a driverless vehicle due to the assumption that the only safe type of car is one driven by a human. Only California, Nevada, Florida, and the District of Coulumbia allow use of semi-automatic vehicles, and they are high restricitve about it. To address how to deal with possible failure in driverless cars, new laws must be drafted to cover the case of an accident. Hopefully these accidents can be avoided, however. Even though the driver themselves is not operating the vehicle the entire time, all manufaturers are implementing warning signals that will alert the driver in the case of a hazard. In 2013, BMW announced the Traffic Jam Assistant, a feature that can handle speeds up to 25 miles per hour by itself, with special touch sensors that make sure the dirver keeps hold of the wheel. Gm developed vibrating drivers seats that warn the driver when they need to take over. Other variables include are flashing lights in the windshield and in possible heads-up displays. Even despite legal setbacks, maunfacturers are hopeful in their development of self-driving cars. Some, like Mercedes-Benz, Audi, and Nissan hope to have these types of vehicles on the road by 2020. Even sooner, Tesla is predicting a car that can drive autonomously 90 percent of the time by 2016. Hopefully, these vehicles will not just be able to drive themselves, but also us the pedestrians into a safe future.
