Two-Player Technical and One-Player Turret Vehicle

When going through the Passage, I remarked to a friend of mine that a technical while fighting Urschleim would have been awesome. One person drives, the other shoots. In order to make sure single players could have it work, perhaps there could be an auto-turret on one of the buildables, or both players could craft one that attacks while they drive.

I imagine this could be done on the go-kart bench, something with galaxite or solarite-level ingots (as there are galaxite turrets) and then it would allow players to team up in a more unique way for both the Urschleim fight and other things in general if they wanted to just drive around and shoot enemies. I imagine this could also be extended to boats where larger boats for the ocean or extreme water gen games could have multiple people on it.
