Razorfist seems like a better moniker that Taser Face.
The bus sequence of the film has four distinct portions. This is the second.
After the standard toughs are beaten, Razorfist–who has been watching from the back of the bus this whole time, stands up and enters the fray. He slices through the bus brake cable which sends it racing over the hill on California St, at Mason (as seen above).
The bus continues East on California street where it hits a car at the intersection of California and Powell, knocking out the bus driver. It then sideswipes a car near 814 California St. as Sean hops into the driver seat and hangs a hard right on Stockton St. headed South.
Razorfist continues fighting with Sean as he drives the bus and they approach Bush St on Jones St. heading South. Katy takes the wheel from Sean and crashes through some trash near the corner of Bush and Jones Streets.
Razorfist cuts through the divider between the two bus section as the bus approaches Bush St, on Stockton. Katy makes a hard left to avoid the dead end railing and pulls the bus around onto Bush St headed East.
