Actually the limited number of lanes is what enables us to survive the speed differentials. Fast/[middle/]slow lanes can easily be enumerated without counting, which makes situational awareness so much easier. And you certainly do need a lot of situational awareness. It's a bit like CPU registers vs. an unconstrained stack.
I have only ever seen more than three regular lanes in large metropolitan areas where there is hardly any open road between interchanges and where speed limits are a certainty. I don't know if a single piece of four lane unrestricted driving exists in all of Germany, I would not even be entirely surprised if you could not legally build one.
