Example Input: F: I think I should use the bathroom before we go. It's a long drive to the countryside. ,M: Yes, but there are plenty of rest stops along the highway. ,F: I know. I guess this is why driving is much more convenient than taking a bus or train.

I thought you had a driver's license. ,F: No, I've never needed one. I've always lived in Boston and it's easy to get around on public transportation. But now I'm taking a job in Los Angeles. ,M: Congratulations. ,F: Thanks. But everyone knows that to live in LA you have to drive. So I've been taking lessons and I'm going to take my test tomorrow. ,M: Are you planning to buy a car once you pass your test? ,F: Yes, I've already picked out the car. I want a twenty sixteen Honda Accord.
