I doubt we'll see more street racing. If anything there will be another bullshit night on Friday. In reality the turnout on Saturday will be smaller now.
Tell me, it's a nice sunny Sunday and people are cruising around. Just because race city was open on Friday night this is going to stop someone from racing at a red light on Sunday?
"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age."
-H.P. Lovecraft
