Which sentence in the excerpt below uses a hasty generalization?

many young people between the ages of 16 and 18 are involved in car accidents. in fact, about 37 percent of all car accidents involve at least one driver between the ages of 16 and 18, and if you include drivers up to the age of 21, the statistics are even worse. about 45 percent of all accidents involve at least one driver under the age of 21. this means that youngsters are reckless drivers.
clearly, it is time that we change the age at which a person can get a driver’s license. it is time that we make 21 the legal driving age. many young people will scream that this is unfair. they will claim that a job, an education, and a life would no longer be accessible to them. the truth is that without a car young people will find an alternative way of getting around. whether it means riding public transportation, riding with parents, or even old-fashioned walking, where there is a will, there is a way to get there.
