Remember Heaven's door is reading and modifying a person's experience and memory hence as long as a said event is achievable in the JoJo universe then adding that particular "experience" in would be certainly possible to have it work physically/externally.

The logic of Heaven's Door can be very similar to how the Hanged Man works, which by attacking and injuring a person's reflection, due to reflections and the object that are reflected must stay the same hence when the reflection is harmed, so is the person in front of the mirror. Heaven's Door works by the principle that "because the person is experiencing X, so it must have actually happened for him to experience it".

For a person to fly backwards at 70kpm you only need enough force to sent a person into that state, which most large machines such as cars are definitely capable of.

Hence when a statement of "I am flying backwards at 70kpm now" is present inside a person's memory then it would also be true that the person is "experiencing" that now and so, the person is flying backwards at 70kpm as ordered. It doesn't need to include a reason, much like how most people get into a car accident without knowing what even hit them until they hear the full story in the hospital.

However on the other hand, Kira's power is literally just blast through everything it touches hence a statement like that would require something Killer Queen can't damage to exist in the first place, which is impossible under normal conditions hence the modification even though is never tried but theoretically just wouldn't work.

This is my take on the matter.
