Hello, everyone. We will talk about the technology today. You know how much your telephone has changed over the past ten years? Your car will change even more than that in the next ten years. One of the big changes is that cars will drive themselves. Some day you may not need to drive a car. You will just tell the car where you want to go and it will drive itself. " We definitely have the technology for it now, " says Andrew Poliak of automotive technology supplier QNX, " We expect self-driving cars to be a mainstream thing between 2020 and 2025. "
    The American company Google has been working on self-driving automobiles for years. These cars are already on the roads in the United States, mainly in California. An autonomous self-driving vehicle goes onto the road during a demonstration at North Business Park in Singapore on October 12, 2015. Google cars are truly self-driving. These cars have no steering wheels or pedals. Last week, police ordered one of Google’s cars to stop for driving too slowly on a public road. The car was not violating any laws, so no one was punished. But police did speak with the operators of the vehicle. According to Google, its self-driving cars have been driven nearly 2 million kilometers. That is equal to the distance the average person drives in 90 years. So far, no Google self-driving car has gotten a traffic ticket. Some of them have been in accidents when other cars hit them.
    According to the Auto Insurance Centre, 81％ of car crashes result from human error. Many lives could be saved if cars drove more safely without human drivers. With fewer accidents, insurance costs may be lower for self-driving cars than other vehicles. In a self-driving car, you would not have to be worried about talking on the phone or sending a text message. You could do other things while getting to where you need to go. Traffic may be reduced. Cars could flow more smoothly, with fewer cars on the road during busy times. Fewer accidents mean improving traffic conditions, and reducing delays, repairs and injuries. OK, that’s all for today’s talk. Thank you.
