A type of glider, elytra like, attachment that can be added to vehicles would be awesome! Since this is a very "kart" like mod, many kart games have sections of maps where you glide/fly to the next area. This would be a more arcade like addition to the mod, but with the dash/jump/slow blocks and a drifting mechanics already in place this would bring this mod closer to being able to be feature complete for use in kart racing maps.
