I totally agree with gogfeld. I like LRF, especially RAC which is too slow in comparison with other LRF cars, so nobody never drives it, so ti is pointless for me to drive it and be slowest on track... Now on topic... i have played LFS for few years and I got several times into this phase. When I would get bored to lfs i would make a new hardware. First i made a shifter ( long time a go, much before g25 got on market), then clutch pedal, then shiftlight, then LED tachometer, then analog tachometer... and so on... last time i tried to build digital speedometer, but failed... The point is, when i would make something i would be very interested in playing again because of new stuff... You don't need to make something, it is enough to have something new, just to make you want to drive, like new wheel or cockpit. When i got my g25 and rinoseat I spent time in driving a lot. You should try it.
And yeah, you could try not playing for a while and then join some of most crowded servers and you will probably get back to driving.
