Toledo: As far as I am concerned a restricted driver has still not proven themselves in a final test. The difference in driver performance between a restricted test and full test is more than the difference in the licences ie: ability to drive after 10pm and have other people in the car.
This argument makes good sense. If we consider the ability of restricted drivers to be lower than full drivers then allowing a higher proportion of restricted drivers to exist on the road increases risk for other road users. Benefits of new or changed driving regulations are usually measured in number of predicted lives saved reduction in road toll. That is not the case here. It is unusual the govt is not making that case for this change by providing this type of statistic.
Perhaps this change is not justified or motivated by traffic safety concerns. It is impossible to tell because there is no good evidence provided to support it. This is unusual.
