I know, I even responded to it.
However, the Red Light isn't required to be followed by anybody, since anyone can turn off fines and the fact is that the hard turns will inevitably lead to lane-cutting, angry individuals and horn spam as a result of players that should be playing on Arcade instead of Sim 1.
Personally I do not agree with your statement that the revamp has to be done by SCS. As Mischievious Vixen and I pointed out, TruckersMP has already done revamps, let alone adding a whole city. They are very much capable of transforming the intersection into an interchange I have shown above. On your clustertruck point, Duisburg has a highway interchange too, and it is 10x better than the alternative that SCS had pre-September 2022.
