Anything outside of paracentral is considered peripheral. Paracentral is an 8 degree visual field. That’s a tiny potion of your forward vision.
When you are driving down the road that means the sidewalk is in your peripheral vision until around 25 metres ahead. If that’s too late for you to notice something then you probably shouldn’t be driving - at 50km/h, every metre after 25m before you notice a human hazard is 5% more likely to result in a fatality.
