I think that motorcycling requires a mature mindset. For example, in some countries, high-performance motorcycles are restricted to people over a certain age, where they are emotionally mature and do not engage in traffic situations that are dangerous to themselves or others. I think this is a good idea, but only to a certain extent.
Young people in particular often cause accidents because they do not have enough experience. If they have to wait longer to get their license, they may be more mature. This can help. But age does not always mean responsible driving. Some older drivers also make mistakes or drive dangerously. So changing the age limit alone may not be enough.
Another thing to think about is that driving schools should be better. Many people pass their driving test successfully, but they still do not know how to drive safely. The government should make the tests harder, more effective and provide more lessons on safe driving. However, a psychological assessment would also be introduced to screen out those who are prone to breaking the rules. This would teach people to be careful and there would be fewer accidents due to human error.
In conclusion, I think raising the minimum age could help a little, but it is not the only way. Better training and stricter tests would be needed to make the roads truly safe.
