I have heard this argument at brigade level about various things, driving, what age is appropriate for attending fire calls etc etc. End of the day each individual has a choice of being an idiot and making the wrong choices or following the rules and doing the right thing by everyone. I got my licence when i was 16 and I know people who were my age being idiots but also people who were 30 driving just the same and they had a licence for nearly 15 years. go figure, it doesn't matter what the age is people will drive the way their head is telling them.
