Sydney and Rachel (Mockingbird) are trapped in a Jaguar electromagnetically suspended over a car park. Firstly Rachel kicks out the rear seat-back and climbs through to the cabin, which is impossible as the car would have intrusion protection from the boot/trunk, plus the seat back is bolted to the frame. Secondly, Sydney kicks out the windscreen which shatters onto little pieces. All modern cars - especially Jaguar - have laminated windscreens which do not shatter like.
Sydney and Rachel (Mockingbird) are trapped in a Jaguar XJ sedan, a vehicle whose chassis and body are constructed from aluminum. As a result, it would not have been possible to electromagnetically suspend that car.
