An acquaintance of mine who was in law enforcement told me when they stopped allowing LEOs under 25 to drive the more powerful cars there was 90% less wrecks. That has to speak for something - the fact is that young brains are not fully developed and cannot always comprehend or predict the consequences of their actions.
Some can, some can't. Some kids drive well out of the gate, others never really get the hang of it. Can't paint everyone with the same brush, but in general and statistically, kids in powerful vehicles are a high-risk group.
