drunk riding

 I think of dangerous cyclists in terms of drunk riding. Many people such as labor and university students ride a bicycle after drinking. They sometimes drink so much that it is dangerous for them to ride a bicycle. Maybe concentration and attentiveness will decline, so they can't drive safely. As a result, they can cause an accident.
 Therefore, I think drunk riding is dangerous and should be banned. I want to ask people about it and find preventive measures.
