The whole idea that there are a load of Mr Magoos out there driving blindly just isn't supported by the crash stats.
Agreed.
However, I've seen enough examples of poor driving where I suspect the driver has below the minimum standard of eyesight. Most often, the driver is elderly and so poor eyesight isn't the only possibility (I'm convinced there's a significant number on prescribed drug cocktails that shouldn't drive).
That said, the antics such drivers get up to might seem dangerous but they're usually just inconvenience. For example, a few weeks ago I was driving on an extra-urban road after dark and the driver in front of me was doing about 50 mph. Every time a vehicle approached from the other direction, the driver slowed right down to below 30 mph and then sped up back to 45 or 50 after the oncoming vehicle had passed. As soon as I could do so safely, I passed that car, which then sped up to keep station behind me for five or so miles into the next town. I have very strong suspicions that the driver suffered from night blindness (which is reportable). It might be that other drivers are mitigating any danger visually impaired drivers pose, which is a possible reason that visual impairment doesn't figure in the accident statistics.
I'm rambling - sorry, but I hope you know what I mean!
