The quiet ones are the dangerous ones
Obviously, traffic is a problem. I've given up riding a bike a while ago after I've overlooked and rammed a parked car. As a pedestrian, I've got a little more reaction time, because I'm slower. The basic problem is that an oncoming vehicle can be completely invisible to me if my blind spot happens to fall on it.
How much are 10% ?
My eye doctor tells me regularly that my eyesight is at 10%. This is determined by the usual letters and numbers in various sizes, which are projected on the wall. Sometimes you can still see the panels with the many E's showing to the left, right, up or down. The largest are at the top, towards the bottom they are getting smaller. 10% equals the top two or three lines that I can still see. With my glasses, of course, without glasses, I don't see a thing on these panels. But what means 10% then?
Selective and punctual seeing
Seeing is like any perceptive process is selective. We see certain things consciously other we overlook. This is useful protection against an otherwise not hand able information overload. But what astonishes me again and again how punctually people see.
