I know here in PA the penalties get much worse each time someone is arrested for DUI. There is also a device, not sure how often it is used, but the driver has to breathe into the device before he can start the car. If he doesn't pass the device will not allow the car to start. The car won't start in the first place either so if you were thinking just get in and don't blow into it that won't work, you have to in order for the car to start.

I learned all I need to know about life by killing smart people and eating their brains.
