Just observing the situation one would come to the conclusion that this car has left the track and is flying above the track.
And according to the rules the car has indeed left the track, as no part of the car is in contact with the track. ("Drivers will be judged to have left the track if no part of the car remains in contact with it")
The rules also say "Drivers must make every reasonable effort to use the track at all times and may not deliberately leave the track without a justifiable reason. Should a car leave the track the driver may re‐join, however, this may only be done when it is safe to do so and without gaining any lasting advantage."
Flying isn't deliberate, physics are a justifiable reason - losing contact to the track, thus losing propulsion is not an advantage either.
So yea, that car is leaving the track but is not gaining any advantage by doing so and therefore should not be penalized.
