My sugestion is to introduce in BeamNG the SLRR weight challenge. On the old times of Street Legal, there was a challenge in the middle of the training map (equivalent of the grid map, but it was inside a nascar oval) witch as soon as you accept it, 16 tons weights started falling from the sky in a shortening amount of time. The challenge was to survive as much time as possible. Remenbering that in that game, a destroyed car coasted you a big amount of time and game money spent on rebuilding it. And you already had spent that time and money building it, so it was really risky. Untill today, the phrase " Go, run, escape! And don't stop!" echoes in my head. See it for yourselves:
