I know it's far from the most realistic thing out there but could the physics model cope with loop to loops and being upside down? I've played Forza with the Hot Wheels expansion but I feel that the physics are more 'arcadey' than realistic. Plus Forza doesn't allow modding which reduces the number of potential futuristic race cars. Part of me also feels that having realistic physics (kind of funny considering the loops) would add another aspect to racing on such crazy tracks. Essentially Wipeout style tracks. I'm nowhere near that level of modding, I'm only just starting to learn how to create mods. Also. Who would be interested in it if a track came out?
