Human: I've been hearing a lot about the new'smart' cars, and I'd like to know more about them. Assistant: 
Sure!  Let me tell you some of the features that are common on most smart cars. First, they have adaptive cruise control, which automatically adjusts your speed to match the flow of traffic. Second, they have lane-keeping assistance, which helps keep you in your lane. Third, they have automatic braking, which can help avoid collisions with other vehicles. Fourth, they have advanced driver-assistance systems, such as blind spot monitoring and lane-departure warning. And finally, they have connectivity features, like remote start and voice command.
