It's more likely that the sensors in the Uber setup are set for fast processing, i.e., less light per frame, rather than for visual fidelity, i.e., more light per frame. After all, faster processing is more important to a vehicle traveling 60 mph than sharp borders. If the shutter time is set low enough, you would get something similar to what Uber released even on a DSLR.

Also, as others have pointed out the Uber video was from a dashcam. The point of the dashcam was to record events in the event of an accident, not be a high-fidelity visual record.
