I never did like that PeterV guy, as he thought he was 100% right on Heat physics and how cars worked in Heat, when he never made a single mod.
Physics in Heat are just as realistic as any other game out there depending on the cars you are working with. The more time you spend working on car physics, and learning what does what, the more "real" you can get them. The shape, size and look of the cars really have no bearing on anything. Do The Speedsims mods here like SCP, Group C and all the other feel like 3500 pound stock cars to you?
Does the Platinum GP Indy Cars or G3 Grand Am mod feel like Jimmie Johnson's Sprint Cup car to you guys?
Do any of those Team Players mods feel like the original game?
That was one reason I used to get into it all the time with that PeterV joker. He just knew he was right, and had never even bothered to read, learn and work with some of the other physics making gurus out there. He just assumed he was driving a 3500 pound stock car every time.
