just had an thought, in ur opinion or i should say in ur personal canon, which pixar films you can easily see beign set in the same universe as a previosu pixar film
like lets see Toy Story could take place in Monsters Inc continuity (which in fact they do in a comic books) or Nemo could take place in a bugs life continuity etc etc
obiously Cars is on its own universe (due of living cars of course) so it cant co-exist with any pixar film comment and tell me ur personal canon
