I believe there should be an option when sharing a tune or a livery or a vinyl group that asks if you want it to be locked or unlocked. That way if you want your tune to be your own secret recipe you can still have people download without knowing what parameters you used but if you dont care than people can download the base and alter it to their liking. Change rims, aero parts, alter suspension for their playstyle, drop aero and incrase gearing for speed races, whatever…
