You can fly your car for a short while in NFSMW. When you are in a race then try to run your car at maximum speed wherever there is a elevated road or wherever you have to go up on the road because after a elevated road there is always a sudden downfall in the road. So your car will fly for some time in air and it will show up in slow motion.
