Start Drivers training at a older age then 14 and 9 months

I don't think teenagers should start drivers training when they are 14 years and 9 months. People believe that at that young age they do not have responsibilities. Even though they are on the roads with their parents, its risky to put a teenager on the road that young. They have not reached full maturity yet and they would probably take advantage of their freedom. They should change the age to 15 and 9 months to give them another year to experience more responsibilities and become more mature.
