Driverless cars to hit the streets in the coming decade

Google’s new driverless cars are becoming more and more popular on the streets of California where they have been test driving the car.  Modifying the Toyota Prius to operate as a Google driverless car has turned a corner on technology for Google.  After it passed the test course on mountain roads, the goal has now shifted to mastering city street driving.
A car that can drive itself is the latest in auto technological projects.  With jaywalkers, lurching cars, and blocked views, a typical city street can leave even the most experienced drivers irritable.  A mile of city driving is much more complex than a mile of freeway driving, with hundreds of different objects moving according to different rules of the road in a small area.  There are many pedestrians, buses, and bicyclists.  Google has made sure that this new self-driving vehicle can pay attention to all of these things in a way that a human physically can’t—and it never gets tired or distracted.  By improving the software, Google has made this car able to detect many distinct objects simultaneously to make it as safe as possible. 

Driverless cars must be able to plan a route and navigate through traffic safely without hitting other vehicles or obstacles. In order to accomplish this, they must be equipped with computer programs, radar sensors and Global Positioning Systems (GPS). The public already has access to some of the systems used by driverless cars. An example is the Automatic Cruise Control in more modern cars.  This enforces distance between a car and the one driving in front of it. However, driverless cars have the added advantage of technologies that the public doesn't have access to yet. These technologies enable them to sense other cars, give or take the right of way on the correct occasion, or arrive at an intersection and stop.

A huge debate over driverless cars exists between major car companies, like BMW and Audi, and possible buyers everywhere.  Although driverless cars sound intriguing, they are still somewhat frightening to today’s drivers.  Whether or not these cars will be safer has not yet been proven.  With continued enhancements and trials, consumers may eventually become comfortable with the concept.


Google expects driverless cars to be pretty common by 2025.  The expected release date is in the next three to five years.  Even though there are many questions regarding driverless cars, driving on busy city streets might be made safer and easier.
