FSX’s collision system has one thing going for it – it is super fast.So it’ll be interesting to see if they do decide to burden Flight with a more elaborate system.Possibly there is another solution which is making high res AI paths with a vertical-Y component.This would be relatively quick…but very-very bug prone.People complain about wheels breaking into the ground already (not really an FSX bug...it's an art bug).Good paths might be made, but they’d take a lot of work and data.My guess would be they prototyped this solution years ago…but couldn’t get good results...

Not just "could be rectified," but had been until development code for FSvNext was archived and the entire ACES studio closed. One of the goals was to develop independent suspension for vehicles, which meant developing a scheme to detect tire contact with the mesh layer. Had this been completely developed, it would have provided the means for AI to track ground elevation changes, which in turn might possibly have enabled the reality of non-flat runways being implemented.Of course, nothing comes without cost, and it may well have been too computationally intensive keeping track of hundreds of "wheels on ground..." :(

LOL at "wheels on ground..." "looking like a fool with your wheels on the ground"
