Driverless cars are becoming popular due to the technology that is being developed.  Car companies are coming out with vehicles that can sense and navigate everything around it without people operating the vehicle themselves. 
Driverless cars should not be put onto the road yet because of problems with weather conditions and obstacles on the road.  Some sources say that the vehicles don’t know what to do when it comes to unthreatening obstacles in the road.  Although driverless cars sound like they would be a good idea, there is not technology advanced enough for driverless cars to be completely driverless. 
In a blog post from Esurance, Ellen Hall stated, “Google’s car can do a lot of things -- keep a safe driving distance, find a parking space, brake to avoid a collision -- but as of mid-May, it still couldn’t obey road signs or handle poor weather conditions (and there are conflicting reports about whether it can recognize pedestrians).” Hall also said that, “This mapping already exists in GPS programs like Google Maps, and it’s getting more sophisticated all the time, but occasionally it’s just plain wrong.” 
Some people think that driverless cars will be a safer alternative since most accidents happen because of human error.  If driverless cars are going to become more and more popular, the companies should make the cars perfect with no flaws.  Anyone should be able to drive the cars even if they have difficulties driving due to medical reasons such as impaired vision.
In an article published by ETFinancial, one source stated, “there are a lot of problems to be resolved before we really could have automatic driving on the road.”  A lot of people will be doubtful about these driverless cars because of the technology.  Some of the articles say that while you are in the car you will still need to be paying attention to all of your surroundings just in case something goes wrong.
According to an article by New York Times, Nidhi Kalra said, “In the United States alone, some 30,000 people are killed and more than 2 million injured in crashes every year, and the vast majority of them are caused by human error.”  Kalra thinks that driverless cars are a lot safer than people driving cars.  Scott Le Vine says, “A self-driving car, by contrast, would simply obey its pre-programmed algorithm - opening up the algorithm’s designer (a much deeper pocket, in the jargon, than the individual hapless motorist), to a host of novel legal and ethical questions that we are just beginning to grapple with.”  Le Vine thinks that with all of the technology coming out that these cars will be safer and better than any other cars.
In conclusion, driverless cars are not and will not be a safer alternative than people driving cars because of the current problems they have unless they advance the technology enough for the cars to be completely driverless.  These cars may seem like they could be dangerous.  For example, what if something with the technology goes wrong.  Driverless cars need to be made perfect or not made at all.
