I have a Model 3 Performance, so obviously the worst in this respect and to be honest, I don't have a problem with approach and departure angles. I live in an extremely steep and hilly area with stupid road entrances and driveways everywhere. Even driving out my own driveway I have been known to lift wheels. Basically the "wheel at each corner" approach of Tesla means that approach and departure will rarely be a problem.
Ramp angle is another matter altogether. A low slung car combined with a very long wheelbase for the vehicle size means that it is quite easy to belly drag the car going over lumps, aggressive crests over driveway entrances and so on. Never going to be a problem on a normal road, but driveways are a different matter. Fortunately, the undercarriage is pretty smooth and well-protected so you are unlikely to do much damage.
