Guy on the bike was an idiot. Not for running necessarily, but for staying straight on the same damned road for so long! GEEZ! You don't outrun the law, let alone the radio, by staying on the SAME ROAD! As soon as he broke sight and contact he should have hit a side road, swapped directions at a normal speed, and went about his merry way.
I hope the statute of limitations has ran out, but Ive lost a trooper in a ext cab 4x4 pulling a 4 wheeler behind me! If they don't have a tag number, break sight, change directions, and go on about your business!
