[Q]: M: Would you consider buying a self-driving car? ,F: I don't know. I guess I'd have to research a bit more about them before making that decision. ,M: It will probably be a while before we are able to buy them anyway. We might be seeing self-driving trucks on the road pretty soon, though. Google wants to change the commercial trucking industry. Right now, there are over 3 million truck drivers in the US, so adding self-driving trucks would likely take away a lot of jobs. But many drivers might still be able to accompany their trucks and get a full night's sleep in the process. ,F: Truck drivers cause a lot of accidents on the freeway, so I think I'd like to see self-driving trucks. It would make me feel safer on the road. ,M: Really? I think it might make me feel less safe. A human driver is much more likely to react quickly to something unexpected.
(A) F: I am not agree with you, I don't think they are safer. (B) F: I am really sorry, I did not catch that. Would you slow down, please? (C) F: I am not excited by their speed because I think they are not safe at all. (D) F: Are you serious? I don't understand why you feel scared by them.
