I remember when I did a course called 'Emerging Technology ', a project was given to a group of people. And they were given a project on driverless cars, it's functions and its operability. My major concern is the area of security when it comes to driverless cares. Though research have been carried out and their results was that driverless cars would reduce accidents. In future we would know very well it's effect . Another, is the implementation especially in developing countries. It would take years for it to spread around the world. Because relating everything about driverless cars, it depends on the Internet of things. Great article buddy.
