perhaps a stupid question but why haven't they decided to simply drive the opposite direction?
The tracks are normally designed to run in just the 1 direction, so things like barriers, run off areas, grid slots, starting lights, digital flag boards, access roads, pit lane lights, marshall posts (where the barrier opens with an overlap), etc. will all be facing the wrong way.
Some tracks can run backwards, they are normally tracks that look like a supermarket car park with some lines drawn around it. These are much easier to reverse because they don't have to deal with moving physical barriers, just move some tyre walls around and turn all the lights around.
