One way of getting an indication is getting data from other cars and somehow out that into a model to get some indicators.
Maybe combined with some kind of lidar cameras around the track to spot small differences in hight
This would be more for race control and info for the engineers to coach the drivers, I don’t see drivers having some 3D map in front of them or get a number so they know how far they can push. More a warning to not take any chances, like a automatic yellow/red flag.
