Sounds like new drag racing, donut circuses fines going up.
not that i condone it in the slightest, and i offer this as an observation, but the intersections in south LA (at the dount shop) and west hills are absolutely massive, that whole thing at the 6th street bridge is dumbfounding. it's a TINY area and on top of that there's literally nowhere to go. 5-0 could run a drag net with like 5~6 cars and round everybody up. you're hemmed in by the river on one side, the rail yard on the other and all the one-way dual level/dead ends of downtown on the other front.
that's hilarious, they looped back and got jammed up in the tunnel trying to jeep it back to the fwy. they were probably listening to their GPS. haw!
