Would make an excellent oval for LFS bangers, plus other oval formulae as well, would be better than having to construct one using auto x objects on the carpark anyway, i still havent found that bit tho, but i will go look now!
EDIT: found it! bloody barriers blocking it! GrrR!!!
The only oval like part i could find was this one at fern bay, pity the car gets auto reset back onto the main track when you get half way down.
