I wish all cars came with an intercom system. It would be handy when trying to politely inform the car in front of you that the speed limit is actual 45 when they're going 30. It would be handy when you want to honk at the car in front of the car in front of you. And especially, it would have come in handy today. I was driving down the highway, when at three separate times, semi-trucks honked at me and flashed their lights. Or maybe it was the car in front of me. I don't know. My engine could have been dragging behind me, but since these guys had no way of communicating with me, I just kept driving. Paraniod.
