In Virginia, speed over 90mph is automatically classified as reckless driving (and the punishment can exceed the punishment for DUI). I don't know if any of the states he did go through have similar laws.
In Ohio, 20 over the posted limit is reckless driving, but it is up to the police officer. My last speeding ticket was 48 in a 25. While I received two points, I was not cited for reckless driving. My last ticket was "failure to control" because I hydroplaned and totaled my car, traveling 55 in a 70 in heavy rain. It also incurred two points, but was not reckless driving. Typically in Ohio, cops give reckless driving citations in conjunction with something like a DUI, running from police, hitting a pedestrian or stationary object, or a judge may tack on the charge if the law allows it and the officer did not already cite it.
