The real problem is the track, yes the drivers should be better, but if they can they will drive to the edge especially if they’re struggling. The corners which are problematic are high speed, I’m sure remodelling the track slightly would help. Maybe straighten 9 and tighten 10.
Mind you hulk got track limits when he parked his car.
The problem is not the track! Yes they could remodel the track by putting a wall directly on the outside or a strip of grass (or similar) so the drivers lose time running wide and I'd bet everything I own that like magic all the drivers would be able to keep it within track limits all of a sudden.
