Damn that's rough. I saw a car parked in front a fire hydrant at a fire in Queens once. FDNY simply smashed the windows to open the doors, and then ran a hose through it.
That has some "how much pressure can be loss to friction and still provide the necessary water rate at the other end." Bends in the hose will increase the amount of friction and thus reduce the flow rate.
