I thought that was what my extra bikelock cables were for. Interconnect them, toss under potential assault vehicle, wrap tightly over and around cab (through door handles, if possible); if a fire hydrant is near, interconnect another set to the hydrant. If the 'assault' vehicle's owner is about when you return, give a puzzled look like you've no idea... go get new cable locks (usually cheaper than new bike/repairs).I don't trust drivers of four or more, wheeled vehicles, so I never park directly behind them in the Street, (in their blind spot).
