I’ll tell you something you might have not noticed.
Else where on this section of the forums, there are other challenges. Some are open.
An automation forum challenge consists of: someone having an idea, they present it, collect entries, judge/review them and then present the results in a nice manner.
If you want so much to have your cars compared, judged and reviewed, you can simply read those posts and send them a car that complies with their rules.
That’s how it works here. It doesn’t get much simpler than that.
If you really want to be bold, and have someone do the work for you, then please convince them BEFORE posting, so people know what will happen. No one wants to spend 1 hour or more of their life fiddling with sliders for naught. If the challenge dies off, that’s what will happen.
Right now, you are getting backfire because you are a premise for such wasted effort.
You should read these, once you’ve complied with all of that, people will be likely to join you.
