Deaf driver with glass eye banned

[$tevo]

A deaf 83-year-old motorist with a glass eye has been banned from driving for 45 days after he was caught speeding on the A9 in his new car.

Maurice Hollyfield was doing 88mph while towing a trailer on a single carriageway with a 50mph limit.
Perth Sheriff Court heard it was the second time in less than a year that the pensioner had been caught speeding. Hollyfield, from Milton Keynes, had told the court he had been reading the rev counter instead of the speedometer.

I honestly think that in his position, I'd ban myself for life. It initially struck me as a humorous story but really, he could have taken someone out with his driving. Time to pack it in I think.

I bet he didn't see that coming...

so he thought he was doing 7000 mph ?!

Someone should tap up his tacho then?

"told the court he had been reading the rev counter instead of the speedometer."

That's DWDC, surely?

[injury_ian]

also with 1 eye you have no depth perception? surely he can drive not knowing how far things are away from him?

[Spiderman]

ridiculously you are alolowed to drive with just the one eye, its DVLA and your doc who make that decision.
Tho i agree that it shouldn't be allowed as there is no depth preception so stopping distances etc in an emergency situation could be very compromised.

Sorry to correct you but most of our ability to perceive depth does not require two eyes.
It's really only retinal disparity that requires two eyes - all the other depth cues, superimposition, texture gradient, linear perspective, height in the visual plane, need only one eye and a fully developed ability to apply size constancy scaling.

Phew! Just taught my A level students all that so I hope they're reading this site!

To be fair, people with one eye (especially those who lose an eye later in life, rather than being born with one) do have some sense of depth perception. They work it out based on shadow, prespective, size relative to type of object (ie they know a truck is bigger than a car, therefore if a truck and car are the same size, side by side, the truck is further away) etc. The only real situation where they have no discernable depth perception is in the artifical environments of a test. Eg, in a room with perfect chrome spheres of varying sizes, and no shadows, they cannot work out which spheres are nearest the way a normally sighted person could. That's not to say they are not at a severe disadvantage when it comes to driving though...

Edit: Beaten to it by Messie in more scientific terms. :)

bloody hell Messie....send that in to Qi, they'd love to know that info too i'd imagine.
I alway thought you needed both for depth perception...and i've got an A level in biology too :oops:

That would make two of us, but then again I'm more into the hearing part of things! ;)

IIRC there is a member on here who only has vision in one eye & he manages ok on the SV - sorry fella but I can't remember your username :oops: but I remember you being at AR07 - you know who you are! :lol:

I seem to recall Father Ted explained it very succinctly to Dougal....................these (toy) cows are very small, those cows are far, far away :D

[Biker Biggles]

I assume the coffin dodger can pass the required driving eyesight test so why should he not drive?He has been banned for speeding not blindness.I wonder what his accident record is like,as I guess it is probably good.Coffin dodgers tend to get "banned" by the insurance industry once they start crashing the things.

I think you'll find depth perception with two eyes is only really up to 35ft or there abouts. It increases the further apart your eyes are. I remember this being said decades ago back when I was in school, physics I think.

It's slark01, he does pretty well, except when he bottles in going down a hill and 'finds' a nice pile of mud and sheep muck to gently plop his bike into :-P

Yup the depth perception comes from the differential angle your 2 eyes see, less pronounced at distace, similar theory applies to the resolution of lenses, the larger the lens the better the resolution.
This is how these "stereo binoculars" work.

I inadvertently rode and drove with just one operational eye for something like two years. I have serious double vision, and before it was officially diagnosed and corrected with a prism in my specs I just drove around with one eye shut.
