The recent IndyCars at Louden race made me curious, specifically on the ovals.
The CART Factor mod, on ovals other than Indy, could be a very good experience IMO.
Can a server enforce specific "upgrades"? Some tracks, e.g. Twin Rings Motegim, an egg-shaped oval, would/could require the short-oval upgrade option... and putting the same car on the Michigan oval would need the Speedway option (and not the SuperSpeedway/Indy option). The mod doesn't seem to call for specific upgrades at any given track, and the wrong upgrade would not give good results.
CART Factor is insane on ovals (TRY IT!) It's a challenge on road courses (another Try It moment, but somewhat tempered by reality here.).
Some sequence of tracks, e.g., Michigan, Milwaukee, Motegi, and Orchard Lake, could be a very good back-to-back short-race oval experience (20-laps each, or so?)... IMO.
But, it would call for enforcing different upgrades, "Speedway" v. "Short Oval", apart from any fixed/open setups. Is it even possible to server-enforce upgrades?
Are CART/IndyCar ovals Desirable?
(CART Factor is definitely not a benign tin-top mod.)
