Out of fuel situation in my opinion should not include lap saving.
Ok.  If players runs out of fuel, he'll start from lap 1.
Still need to find a way to stop players leaving their vehicle.  Currently, when you exit your vehicle, your doors are automatically unlocked.  I wonder if I remove the auto-unlock, we'll be loved inside our vehicles?  I doubt it, but I'll try find out.
Can we run a Daytona 500 race again this afternoon?  Really want to see if the lags improved.  Thanks.
