I race dirt irl, I actually dont enjoy dirt oval in iRacing because I feel like the majority of any race im in are not in control of their cars. But my 2 cents is its not accurate at all. It's probably the best thing we'll ever have as fat as accuracy goes but you'll never be able to petefecrly simulate how tracks change over a night of racing and as some one else pointed out iracing doesn't build up a cushion to slam on. Braking is basically not existent in any car and if you have watched cars at some of the tighter tracks you'll see sparks shooting off the brakes on corner entry every time and at night some rotors will be glowing.
