A fabulous post (and good comment section) from Megan McArdle: The Pennsylvania Department of Transportation: Sheer genius
regarding her trying to get a driver’s license and being held up for a suspended license for underage drinking before she had a license.
The really interesting thing is that underage drinking is against the law in the US primarily because we are concerned about drunk driving (drink driving to those from the UK). She did not have a license then, they just waited for her to apply for one before assessing the suspension, 16 years later, long after she ceased to be underage.
