My understanding is that the cars in LFS are infinitely rigid - they don't bend at all. This is impossible in real life, even if the chassis is reinforced as is the case with racing cars. Road cars flex even more than race cars.
Yes, I know that it takes massive amounts of processing power to model the bending the way it is done in Rigs of Rods.
Anyway, my idea is to add just one pivot point to the middle of the car, so that front and back can rotate a bit in relation to eachother. Maybe another "axle" lengthwise.
I guess this would be MUCH easier on the poor processor. This does not IMO have to be represented visually in any way, saving further power in form of less polygons to deal with.
My knowledge of vehicle dynamics is very limited, so feel free to point out the flaws in my reasoning.
