The video quality is up to full HD quality, MUCH MUCH better than Deadliest Catch. All of the aerial footage are awesome, full HD quality.
The footage taken at stations and certain fixed locations are also full HD. The rest video quality is OK.
But, the subjects and actions inside every day driving are very poor. You hear same words, same dialogues, watch the same things over and over.
4 star is only for the video quality. The rest is not so entertaining.
