Well, I can tell you, that suspending or permanent revoking of a license will not solve it. I knew one guy (This was in 1977) and he'd been
busted 7 times for DUI. He still drove.
I worked with many people with suspended licenses and they still drove. The WORST part? Few held insurance as you get a DUI you can expect a price of 3X the normal cost.
So, they will do so until they want to stop and change their life and actions.
That's why I always carried PIP (Personal injury Protection) and "Under/uninsured" riders and always was careful about my actions.
NOTE:While I was working and driving, I carried a $300,000 policy if I hit/killed someone. After all, that's not alot, but if I was at fault, the survivors would have some cash to see them through the moment.
