Of course there are undoubtedly accidents where an impaired, distracted or teen driver was the cause without being in the accident. There's no evidence to suggest elderly drivers are unique in that respect. So largely a wash in 'the stats' - unless you have better stats to corroborate your POVs.
And where would we get stats on elderly drivers who failed their vision test and continued to drive w/o a licence? That's what is relevant to the discussion here.
