It seems that every time a vehicle is chosen to be put into the game, it’s at random.
It would be a lot more fun if there were a certain type of vehicle the forum should suggest every few days, as opposed to the disorganized sea of various vehicles being suggested.
This way, the players would have some sort of guidance with what the developer wants, and I think it would yield better results to think of something in a specific category rather than just thinking of any vehicle.
When options are wide, the mind thins itself out looking at everything.
