The optical flow mode in the first video doesn't look like optical flow at all. I would assume in an optical flow mode, the color coding would either show the velocity or the direction of the movement. But on each car/truck one can see all the colors... It looks like the colors just show the "age" of an event, which is a display mode that Tobi Delbruck implemented about 10 years ago. For the low light, it would be interesting to know to which camera they compare. Is the better low light performance not just due to much larger photodiodes?

What's the sensor size? And the optical format?
