Eventually, Dominique will take the red car up a ramp, and two cars will follow. One will be automatically knocked out of commission, but the other will be following still. When you get command of Bond again, look for a blue mark on one of the steal beams and shoot at it. This will knock some of the structure down, taking the other car out of commission that was in pursuit. From there, an FMV will take over. Two enemy cars will do so much damage to Dominique's vehicle that Bond rescues her from the car, and then the two jump into Bond's car (as Q has it remote-controlled and ready for you!)
