The question was an example of a person displaying his stubborn
insistance that he knows he is right without tryign a simple test.
I'll take the word of a eye surgeon over someone posting on the
internet any day. I'll also stack up my personal experience against
someone who won't even step out the door and close one eye.

I can add an interesting example:
I had the sight completely ruined in one eye at the age of 9 as the result
of being hit directly on the eye-ball with an object that someone was
swinging around.
Some years later I applied for a private pilot's licence and was told that I
had no hope as landing an airplane required perfect distance perception. I
took the regulator 'on' and after many hours of take off and landings with a
Government flight 'tester' sitting next to me I was permitted to continue
with my licence which I obtained.
After the accident, and many years later, my eye specialist informed me that
my brain has learnt to compensate for the missing vision in one eye.
I enjoyed flying that much I built my own 747-400 flight simulator.

Your "Test" is a crock based on your perception and has no scientific
measurement. Your perception is what is in question.
You still didn't answer my simple question.
With no depth perception further than 20 feet how do the golfers hit the
ball accurately onto the green?
All your stories are an example of a person displaying his stubborn
insistance that he knows he is right without answering a simple question.

Since you can't seem to read a simple sentence. Golfers do not gauge
the distance to inches, not even feet. Check with any experienced
hunter and they will tell you they can't measure that close either.
That is why they use range finders (they are banned on golf courses
IIANM).
Again, my eye doctor trumps your refusal to even try it out.

Martin,
All true, and should weight into people's decision to buy a scooter,
for me it was kind of the same thing with dangers involved with eating
food, drinking water, breathing air, having sex... life causes death.
George Carlin said "the kid that eats the most marbles dies", I'm not
suggesting that people do stupid things (wouldn't stop them anyway),
but I've never had an accident off the race course, so I think I've
handled road risks pretty well up to this point, but would certainly
be safer in a pimped out M1A1 Abrams but the fuel mileage sucks.
This isn't for everyone.

I aplaud you for the economy part of it but
The danger logic is very poor. Danger is not on or off. It is an analogue
quantity. Too many of my childhood friends are dead and really f*cked up
from motorcycle accidents, unfortunately. Some were expected and some were
not. One never been on the back of one before. One ride **sigh**
Enjoy it and be careful.
