The thought of driver less cars also makes me a little uncomfortable. I do agree that there are many, many drivers who are out there who shouldn't have a licence because they are often distracting themselves by either texting, eating, etc while driving, ultimately putting everyone around them in immediate danger. In the article, Driver less Cars Get California License, it talks about cars with CPUs have already been tested, and given approval in California. This "eaks" me a little bit because it may seem a little safer, but what if someone who doesn't have a "smart car" blows the red light when the computer is telling your car to go. With computers, it may not consider reaction a human may have. Could it reduce accidents? Maybe, and I honestly hope it does.
I think humans are most likely to make errors. That's what makes us human, the errors we make. Technology can reduce these errors significantly, and has as it changes.
