IMO... The real issue is not the "Street Racing" and safety.
Statisticly, it is simply not significant as a cause of death for young people.
This is about a far more serious trend that I see. The ability of local Police to infringe on your rights.

I see an overall bigger picture here which amounts to the "camel's nose" under the tent,- meaning if Riverside gets away with this potentially a Street racing modification will be viewed the same for a Honda or a Big Block Chevy.
The Police will see no difference when your car is being towed.
