Agree, was funny to see the words "new worst".
I had more fun going fast ;). It felt good to do!
Improvements for racing games (whether worst or not) for me all revolve around polish. Add craft floating (slight bobbing up and down), crash physics, stop the trails from intersecting with the craft.
I like the interpretation of the theme. It's simple and works.
I was going to say that the optimal strategy is very obvious; but then again it is for normal racing games! So that's not a problem.
I think the main issue is that no matter how you are doing, you have health left at the end so you are encouraged to just run into a wall until you almost die, then finish. Which is a bit boring :).
Perhaps at the end you gain time based on how much health you have left.
So to get the fastest time you have to be almost dead. Then people who do the sport called be "devastators". And you're trying to lose on purpose, so you're a "dirty devastator". I dunno, it captured my imagination lol.
