The Tow Truck chasing John Connor in that Los Angeles canal in "Terminator 2: Judgment Day" (1991) was too tall to fit under the bridges, so director James Cameron just cut the roof off on camera.  Every frame of film in that stunt was real.  The truck smashed through a a fake wall hiding a launch ramp - plunging thirty feet onto bare concrete.  The canal bridges provided nine feet eleven inches of clearance, so they pre-rigged the roof to shear away the instant it hit the first bridge.  The truck’s landing also blew out both windshields, yet moments later, Robert Patrick is seen calmly punching the glass out of an intact windshield frame.  That continuity slip bothered Cameron for 26 years - until he digitally erased the flying glass for the films 2017 3D re-release. The finale needed a center divider for the truck to hit - so the crew poured a concrete one themselves and destroyed the truck for real.
