Well if you read the article, a witness said that the car that rolled over had ran a red light and a car turning left hit it. Could have happened at any intersection. 7 by 5 lane is wild is indeed wild though.
The more lanes a road has, the more lanes a turning car needs to cross, the more time spent in the intersection. Obviously running a red light would most likely hit a turning car at any intersection, but the odds of a collision in this case is higher as a result.
