That doesn't sound very plausible given the description from the neighbor who found her. The only injury he saw was a large, bloody wound to the back of her head. She was laying face down, half in the street, half on the curb. Seems pretty unlikely that someone could fall and sustain a severe head injury on the back of their head, then be able to roll over on their stomach. Usually, when you sustain a fatal blow to the head you're not capable of rolling over onto your stomach.
It sounds like she was struck from behind, either with a weapon or possibly a gunshot, then fell and died where she was found. The neighbor also said the cell phone and liquor bottle were placed some distance away from where she fell. It's not specific, but it sounds like it wasn't within arms length.
If she had been struck by a car, she would have sustained other wounds. There likely would have been other evidence at the scene. One can also assume LE would have an answer by now for COD if it was simply an accident.
For now, I'm going with the statistics and probability. So far everything in this case implies the husband killed her in a fit of rage. LE should have enough evidence by now to determine whether or not the husband was the killer. Regardless of her hobbies and lifestyle, no one deserves to be murdered in cold blood.
