A friend of mine did this to me, but I was driving a Citroen BX with a FRONT wheel handbrake... I didn't crash but nearly did, I nearly left my friend to walk home too.
Anyway, here's mine:
You explain your morning dopeyness as fps lag - TRUE
You refuel your car and wonder how much % you just put in - TRUE
You seek out excuses to left foot brake, like traffic calming chicanes - TRUE
You see FXO on the number plate of the car infront and just stop yourself from explaining to your passengers that if it was a real FXO it would have a 2.0 litre turbo charged engine instead of a 1.4 - TRUE
You excitedly explain to a relative about your last league race - when they point out 'this is in a game right?' - TRUE
You know when you've played too much LFS when you...
-Find a bug on the ground and quickly patch it.
-exit a roundabout, then find yourself tapping on your passenger's leg as if it were a keyboard.
-Constantly press "F1" in MSN intending to paste a smiley, when infact you accidently open the "Messenger Help menu"
-nearly buy a £300 camera because it has "FZ5" in the name.
-someone bumps you at the traffic lights - you quickly turn to them and call them a wrecker.
-Park up in the petrol station and just sit there waiting.
-you sprint down your hallway making the FXO soun......nevermind.
...you call your car a XFG when its really a Punto
...you see a white car and shout "you forgot to upload your skin!"
...you walk into Halfords asking if they have Bespoke for your car
