General Science / How good are sight tests as a guide to driving ability?
« on: 10/07/2015 10:42:56 »
When I have to renew my driving licence from time to time, I must undergo a visit by a doctor, who, using the usual table with letters or symbols getting smaller and smaller , until he decides that I'm "almost blind" and cannot drive a car.
After leaving the place, I start driving and I am sincerely sure I'm able to see every detail of the environment around me, a bug crossing slowly the street, leaves on trees, read an advice stuck on a tree , the model of the bag of the old lady crossing the road.
This makes me very upset. How could the doctor argue I cannot drive?
I am a physicist, so I like to compare experiments. This one is like measuring something using two different methods. Suppose to have a pot of boiling water, putting a thermometer in and measuring
60 degrees Celsius. One of the two concepts is obviously wrong : water doesn't bubble or the thermometer isn't good? Unfortunately the doctor will prevent me to drive, according to awrong concept Thanks, Paolo
