you should release both of these tracks
/bump
I will eventually, but Rainbow Road uses HackPlant bricks, so you might wanna download the addon first in order to see it. Also, the white tube part at the Rainbow Road track is made so that only BotKarts and other Bot vehicles can float up it. Any other vehicle goes apestuff crazy in an attempt to go up, so if you want to make it like FASTKarts or something, you might wanna fix that.
Anyway, here is another track I made, Rotondo Raceway
