Holy poop, these challenges are hard as hell. Or rather, hard as hell to complete while trying to go fast. I got super frustrated, but I did enjoy it :) The sky roads are awesome, and I love that you used a good variety of custom cars for this scenarios. You should upload the configurations of the cars as mods to download!
As always, great work with your scenarios, Bob :D
I made a video of this, and your ludicrous loops scenarios :) If you search for me on YT, you'll find it. I don't wanna link it and be accused of shameless self promotion. I have many things I'm ashamed of, thank you!
