Well you need to have some distance otherwise you have issues with clipping. The further from the origin of the track you are, the bigger this distance needs to be to avoid the clipping, so its always a bit of a compromise between having text 'floating' and having them flickering on bigger tracks.You've just reminded me of something I've always wondered about: why do so many digital digits appear to float a good distance in front of their actual displays in some car mods? Lazy conversions, probably - but what causes it?
There's also the occasional issue where a speedo needle is sticking out like a sundial. I'm always scared of poking one of my eyes out under heavy braking in VR.
And because this is largely going to be used on the Nords, which out of the Kunos track has the most issues, I do also have to have a reasonable margin. I'll make sure to tune them all to suit the Nords whilst keeping the floating distance to a minimum
