Just as a reference, I found this statement in a thesis [1]:

> In the event of a collision, neither drivers nor passengers are willing to admit to engaging in street racing. This can partially explain the low incidence of casualties due to street racing reported in the literature. For example, the Office of Traffic Safety in California, in one of its recent publications, acknowledged that fatalities and injuries due to illegal street racing are significantly underreported due to the issues with reporting and suggested a need for a reporting system reform.

Basically, in some of the crashes, the participants are unlikely to call 911. And it's possible that some of the normal (non-street racing) crashes/fatalities are actually street racing-related.
