A few weeks ago I read about a crash caused by an old lady who tried to over take a tractor but couldn't go fast enough and ended up knocking a lady off her bike. Her husband then ran over his wife and killed her. It was one of many incidents I have heard of where people of a certain age cannot drive fast enough (or safe enough) to be on the roads. Yesterday I saw a man on the motorway doing 50mph in a brand new landrover. My own Grandfather gave up driving on the motorway when he felt uncomfortable driving the required speed - sensible, but others will not want to lose their "freedom" so won't make such decisions.
Shouldn't there be some sort of competency test around age 65/70 to test you are still able to see far enough, drive fast enough on a motorway and so on? Or if deemed fairer, maybe we should all have to do one every 10 years until we reach 65 and then it becomes every 5 years?
