The normal human visual field extends to approximately 60 degrees nasally (toward the nose, or inward) from the vertical meridian in each eye, to 100 degrees temporally (away from the nose, or outwards) from the vertical meridian, and approximately 60 degrees above and 75 below the horizontal meridian [2]. In the United Kingdom, the minimum field requirement for driving is 60 degrees either side of the vertical meridian, and 20 degrees above and below horizontal. The macula corresponds to the central 13 degrees of the visual field; the fovea to the central 3 degrees.
This is like groundhog day!
Above is the field of binocular vision. The "peripheral" vision outside binocular extends to 80+ degrees either side of the vertical meridian.
The dimensions of the black top and side walks are in an earlier post of mine. If you don't believe me then measure off Google Earth and sense check against familiar objects like motor vehicles (data sheets giving dimensions for most popular vehicles are on the internet). Presumably most can handle a bit of simple trig. Then calculate no need to guess. Are you aware of the hearing screening test carried out on children? It some what negates some theories or do posters believe the experts on hearing have it wrong
