How can this be legal?

Modern cars with modern equipment on modern interstates (at least in most parts of the country) can travel in excess of 70 mph very safely but I digress...

What this case comes down to is two different jurisdictions using the same term to describe two different offenses. This man was accused of a lesser offense but because of the term used he is being punished for something he did not do. It does not surprise me that D.C. would be pulling something this.
