Because some people own multiple vehicles that have multiple drivers. I currently own 2 cars.

Also, there are things in place to restrict and make it impossible to drink and drive, like an interlock. This lady should've had one, but I'm betting her being suspended doesn't matter to her and she wouldn't even bother getting one anyway. At risk of being jumped on, I'll just go for it. I have a dui (got it while sitting in a running car, so no, I wasn't driving at the time), and this is my situation. My license is suspended and I can't drive until I get my license reinstated and have an interlock in my car.
