LFS is not arcade game. I remember hundred years ago when I got Gran Turismo 1, after few days of playing I was already very good in it.
Then lets take this LFS; I have done over 200 thousand kilometers online, and I still cannot reach top 15 positions in FM GTi Thursday with those Gti cars.
LFS is very demanding racing environment, since there is mostly just very quick simracers left in this community. Think you buy a real formula one car, and you begin compare yourself to real f1 drivers. Then you say practice doesn't work.
Practice works, but you need also patience. You want success and speed, but sounds that you are not very interested on learning how to achieve that.
