Next episode you should try the drag barstow(it's actually pretty good to drive imo) moonhawk, or if you're feeling like something extra dumb increase the power of the cannon and add some more gears but keep the standard tires, wheels and diff.
If you ever feel like switching up your maps and you keep doing this series, I am making a large map in BeamNG called Cliff Mines, and will be a map consisting of roads and different environments all in the same map. Its quite filled with hills, and all the roads are being done in the terrain editor, meaning that its also going to be more of a challenge to drive. A release is a long ways off, but shouldnt take more than a month or 2 to make a test release thats playable. I like the video you put up. Sounds like you did the voice over after the filming of the runs?
I got the feeling thats what your inspiration was, but imo you should stick to only one map at least for a while, and just out of curiosity how often do you plan on making more videos?
