At present, in terms of danger, lots of human lives are threatened because of ................. driving.

Another very interesting technological ........................ in this issue is that these cars would be able to communicate with each other, and with traffic as well, so the flow of traffic would be much smoother than now.

It may lead to fewer ........................., which is a rather positive side effect as cities are jammed with cars in rush hours.

Did you know that over eighty percent of accidents occur because of human error? In the

case of a computer-driven car, the human ........................ would be taken out of the equation.

So, safety seems to be guaranteed, and we might as well start thinking about increasing the speed ........................ once we see the advantages of self-driven cars.

When we talk about accidents, I doubt whether we can ................................ all of them. I mean, I'd like to think so, but there is no proof of that self-driving cars will not make mistakes. And suppose there is an accident, who is responsible?

Last but not least, the biggest disadvantage in the long run would be the ............................ of humans to operate any vehicle once something happens. Imagine that the AI breaks down in the middle of nowhere, and you would have to drive yourself, but you have no idea how to drive.

So even if we had driverless cars, we should still require people to have a .......................... and make them practice a certain amount every year.
