Street racing just has too many liabilities even if you are on an open section of road in the desert. It was a Mustang, what if he spun out and hit you when he floored it?
I drive my car like I stole it, but there are way too many cops, cameras, deer, and other things on public roads to worry about making street racing not worth it.
