1. Pit system improvement. More options, e.g add x% fuel at stop, Repair damage y/n, change specific tyre(s), server forced tyre change, perhaps aero changes, etc etc, basically anything we can think of, they hopefully will also have thought of.
2. Weight balancing to finally remove this whole LHD vs. RHD joke. Yes people are still swapping the sides we drive on to suit the circuit. Either make the cars RHD or LHD only (as they would definitely be in a real one-car series), or balance them so they are
exactly the same no matter which side you sit on. I'm tired of people arguing that it's realistic as it is, because it obviously isn't, but I won't argue if you want to write something about the realistic way weight distribution is affecting handling after not fully reading/understanding my post.
