There exists a number of at-fault accidents you can have before I say you should simply be barred from ever accessing it again. That number is 0. Any higher, and consequences are needed. Think about every other license out there. Go out and shoot someone? That gun license is going bye-bye forever. Kill an endangered species? Probably losing that hunting license.

There exists a number of not-at-fault accidents you can have before I say you should be barred, too. Because even if you're not officially at fault, chances are you're a contributing factor if you're so far above the norm.
