It makes no sense that in most places 15-year-olds are not eligible for their driver's license while people who are far older can retain all of their driving privileges by simply renewing their license. If older drivers can get these renewals, often without having to pass another driving test, then 15-year-olds should be eligible to get a license. Fifteen-year-olds typically have much better eyesight, especially at night; much better hand-eye coordination; and much quicker reflexes. They are also less likely to feel confused by unexpected developments or disoriented in unfamiliar surroundings, and they recover from injuries more quickly."

Could any one can help me find out flaws in the argument?

I just found one flaw in this argument

That is: the author assumes eyesight, hand-eye coordination, reflexes... are criteria to be eligible for a driving test. therefore, the author argues that because 15 year olds are better than older people in these criteria; they are eligible. the author fails to consider other things besides physical health to allow 15 year olds take driving tests.

Can any one help me find another flaws. I really appreciate your thought.

Thank you!!!
