I had to look up the details -- Germany actually uses a mixed proportional system. Each person votes for their preferred candidate in a local race and for their preferred party. Half the total seats are filled by the winner of the local races -- and the remaining half are allocated in proportion to the party votes in order of a pre-determined list of candidates produced by each party. For some parties -- the order of the candidates on the party list is voted on, for others the list order is decided by some central power broker. I guess this means the local races could still be gerrymandered -- however with more total parties I think gerrymandering might be harder to preserve in general ...

> Half the total seats are filled by the winner of the local races That's not quite true. The seats are distributed by party votes, but if a party wins more local races than it would get seats from the party votes, the size of parliament is scaled up, preserving the ratios until the party has seats for all their local winners. (Which is why the current Bundestag has 631 seats, despite the "base size" being indeed 598, twice the number of districts. And yes, that growth could go pretty high if things go badly, which is why I wouldn't be surprised if the algorithm was changed again). There is also a distribution between states, which makes the entire thing even more complicated. An older model did not scale up with preserved ratios, but just added the "overhang" of local winners on top, which could cause bad effects where votes had negative value. But the base number of seats also was distributed according to the ratio of the second votes. Who gets the seats for a party from that state prefers the local winners, and then follows the local candidate list.
