They apparently were given chances since they were able to repeatedly drive while under the influence.

I've known people to get DUIs after DUIs and not shit was done until their 4th one when they didn't even have a license x_X. If anything I think people who get DUIs should be punished rather sternly after their 2nd one.

Anyways, old people should be retested to make sure they have the reflexes and attention span to handle driving.
