With age comes experience and hopefully some wisdom, but it also means physical aging
It's natural that as we get older, we slow down, some more than others. Our vision, our reflexes and our minds just don't operate the way they did when we were young. Many seniors remain spritely and active well into their 80s and beyond. But many others just don't have the physical or mental capacity to safely operate a motor vehicle.
By no means should we arbitrarily take away driver's licenses beyond a certain age and I hate to see people lose an important part of their ability to live independently. However, being on the road has a potential impact on the lives of many more people than the individuals behind the wheel and just as we shouldn't allow children or drunks to drive, a senior that isn't able to adequately react to the myriad events that can occur while driving should not be behind the wheel.
Ontario is implementing a new evaluation system for drivers over the age of 80 that focuses on safety. Those that have adequate vision and reflexes can continue driving, Those that can't will lose their license.
Frankly I think we should be doing driving evaluations probably every 10 years throughout life to verify you can do it safely, but that's not likely to happen. This is a good first step. ?
