Any other free and open source racing games out there? (Other than supertuxkart of course, though that is a fun game at least to me)

Title says it all, while supertuxkart can actually be pretty fun.. i was curious to see if there were other ones aswell considering from what i remember, there was alot of games that are open source (also try xonotic, that game was fun as hell)

hope this post fits this community since i thought video games are just another type of software in some way (but if it isn't, feel free to correct me if i am wrong as it would be greatly appreciated for the future)

But yeah feel free to drop any suggestions related to racing games, thanks!!
