another workaround to try:
I've noticed that when I accidentally hit ENTER while driving, it releases the vehicle from my control, and it continues on its own, while I am free to navigate elsewhere.
You could get your bike moving in a straight line, position your camera off to the side for a drive by shot, then press ENTER so the vehicles movement no longer affects the camera. That way you can have full control of your camera (but no control over the bike). For a short scene in a video, it could yield a usable snippet. Or not.
