100% agree. I forget to mention that erratic behaviours happened on standard tdf values. Sometimes i feel the lack of an insert in the hdv, a coefficient to trim this effects, but on rF. From a point of view of a coder, it's not so easy to simulate those effects and the forces involved, not to mention the tire deformation and the contact patch. A mess. A F1 is perfect, low pressures, high downforces, incredible cornering and braking capabilities. I remember some stunning slomo of the 2011 season at Montecarlo and at famous Turn 8 at Istanbul. Sidewall deforming, the rim almost touching the ground (was a Red Bull), the tire literally squeezed under the loads. Pressure, construction, heat, the compounds, grip, wear... all those properties to mix. It's a REAL challenge for a coder.
