AG > If the car continues to move inertially right up to the front end hitting the back wall, then both frames predict the car crashes, the garage frame just differs in saying that the back end of the car had already entered the garage prior to the crash (so the car briefly 'fit' prior to the crash). Earlier weren't you willing to consider the simpler scenario where the garage is more like a covered bridge with both ends open, so that inertial motion can continue after the front of the car passes the back of the bridge/garage?
