I'd be happy to help on that latter question. The primary concern for most people is the ability to drive, because it's usually the contingent factor on their employment.
We'll often get clients who come in, for example, a truck driver with a family, and the only way to support the family is by driving. Losing a licence ultimately leads to loss of gainful employment and puts the family in a crisis situation. The ability to drive in a controlled fashion goes some distance to removing impediments in these types of cases.
Now tied to that, and increasingly post-9/11, the imposition of a criminal record has become a significant factor. While years ago I didn't hear that complaint all that often, I'm starting to hear that more now. I appreciate I can't have my cake and eat it too. I think if I took a survey of my clients, the ability to drive would likely still place first, but the criminal record is a close second.
