Motion blur values clipping?

Hi! I have a scene with a car moving very fast on a highway, and I’ve run into an issue where, if the camera gets too close to an object, no velocity pass is generated for it.

More precisely, it doesn’t seem to be caused by the camera being too close to the object, because I tried lowering the FOV and the issue was still there. It seems more like there’s too much motion/speed in certain areas, so the velocity pass just skips them. I suspect this might be caused by some kind of scene-unit normalization that calculates certain values based on the scene’s bounding box cause this road is quite long.

Here are some screenshots and an example of how it looks in motion.

Here’s a Vrayscene with textures, but without the cars.
