Look up 'Sophie Delezio'. Old man ran into her childcare centre, trapped her under the car and burned her to a crisp. Two years later, another old man hit her in her stroller. Twice she nearly died, and was severely injured and disfigured, and both times the old men got a slap on the wrist.
Its ridiculous.
Old drivers are never held accountable for their crashes and they know it and so they keep on driving. State doesn't want old people in prison, knowing their health issues will bankrupt the prison.
Old people never go to prison because they are in 'poor health' or would 'die in prison' and its cruel to send them there, even if they killed someone.
I agree that old people can drive and harm someone and nothing ever happens about it.
