two answers imo
1. join iracing. nothing is free in this life, if you want something of quality, you have to pay for it.
iracing isnt that expensive.
want a nice 42" tv? would you expect to pay what you would have to pay for a tiny portable?
sticking with lfs, could a system be used where your car has to be repaired with credits?
100 for a front wing, for example.
each racer is given, say, 300 credits in their account and have to manage their repairs.
if they run out of credits, they cant repair the car and no racing.
to earn new credits they have to run offline in time trials similar to iracing.
this may teach hotheaded newbies/idiots that there is a concequence to unsafe driving and hopefully being forced to drive clean offline will raise the quality of driving standards.
just my thoughts, now im off for a pretty damn clean race on a certain paying race sim, good luck LFS racers!
