== Conjectural description of Stewart in the intro paragraph...  == 

 The intro paragraph, since 05:00 this morning (11-August) has changed, and now describes Stewart as "hot-tempered". Unless there is some evidence to suggest/prove his hot-tempered nature, then I suggest we leave that out. 

 # A three-time Sprint Cup champion, Stewart is known for his successes on multiple levels of racing, his passionate love of racing, and hot-tempered nature, which has led to many on-track altercations with other drivers.
