Not all elderly drivers are dangerous, of course. And those who get in accidents are not always to blame. Urbanization has led to more aggressive driving in increasingly impersonal communities. More strangers unfortunately means fewer people looking out for each other. Young aggressive drivers and others with road rager create further hazards that with more elderly drivers forms a lethal combination.
Traffic crashes are a matter of public health of epidemic proportions.
The cure is public policy that removes dangerous drivers from the road and personal policy of putting safety above selfishness.
