Lol how do you think they design the cars, back of a fag packet or oh let's guess supercomputer with the latest cfd software doing hundreds of design iterations, of course they model the flow at the back of the car.
Of course they model it using CFD for car design; they don't do it in the simulator. It's far too complex to be done in real time, not to mention that CFD time is limited for the teams.
Although Lando is the only one suggesting the car feels rather loose at the back, like an F2 compared to last years F1.
Is he? I thought I read quite a few drivers saying the same. Actually, that's one of the things I'm hopefully for: if these cars are more of a handful to drive, we should see more mistakes.
The only thing I would add is that the simulators are only running car models so far, none of that data has been corroborated or calibrated against real world data, which could change a lot of parameters quite considerably.
Good point.
