I don't care about how the aero looks, but what I DO want to see updated on the current BF1 is better looking suspension parts so it doesn't look so horrible. Just look at those massive tires, being held on by plain looking sticks? Doesn't look possible. Somehow I think the BF1's track width isn't correct. It looks a tad bit too wide to me.
Also, physics wise I personally think it just doesn't act like an F1 car should. Yeah yeah... all this about "have you ever driven a modern F1 car???" --- don't be stupid, nobody on this forum ever has. Fact is, the BF1 drifts and slides far too much, and the car is thrashed around so hard when doing quick laps that it just looks stupid in the process.
The rFactor BF1 is far better in terms of looks, sound, and feel, and LFS's BF1 seriously just looks and feels like a toy car rolling on a linoleum kitchen floor.
Yeah it is great to have an F1 car in LFS, but the BF1 feels like it was rushed into LFS. It could use some more work to make it an even more enjoyable thrill to drive.
