this dude here has got a high-powered bmw m3. he is ripping through the streets. thankfully he is slowed down by this red light. jams on the break. she puts her hand up on the dash board to catch herself. as soon as the light turns green, he's off again. >> now how impressed is she? really? you can't kind of spread the blame here. watch what the cab driver does. he pulls a u-turn in city traffic from the far right-hand side. >> but look where the bmw was when he started the u-turn. he was hundreds of feet back. ridiculous. >> very difficult to judge somebody's speed when seeing them in your side view mirrors. >>> this is a pretty fantastic wintertime phenomenon. this is in grand haven, michigan. you have ice balls forming in the river surrounding what are known as ice pancakes.
