I wonder how they're distinguishing between passengers and drivers

Its illegal to travel at that speed on that road. We have evidence that you were travelling at that speed on that road. You are guilty. We don't care how you did it. Its not really our problem if you weren't the one driving. You should have asked the driver to slow down. Only criminals have something to hide.

Heh... Only it's not Illegal to travel at that speed... Its illegal to operate a motor vehicle that fast.
