Technology in vehicles has seen amazing leaps in the past several years. Only eight years ago things like Bluetooth or WiFi in vehicles were not standard. These amenities were only reserved for luxurious vehicles are standard in even the most economical model of cars now. Companies like GM and Ford purchasing self-driving startups and expecting to release new vehicles in the next few years with self-driving capability.
Companies like Tesla have had self-driving vehicles for a few years. And even Google has experimented with self-driving technology. There have been some hiccups and a few other misuses of the technology. This should not stop the progress of the technology. The technology is still in its early stages but I would expect the minor things to be fixed within the next few years. Many other major car manufacturing companies are predicting to have a self-driving vehicle within the next few years.
While its too soon to tell how this technology will affect future traffic laws, it is likely to make some marvelous changes in the future. Road trips will definitely change with such advances. It can only be hoped that it positively affects us more than any harm it might cause in the future.
