The absurdity of the proposal is already in the title, and shows how motonormativity is spread all over the world.
Berlin has a very good public transit system, and a few 30 km/h zones cannot be that bad.
I would love to hear opinions from someone who lives there!

Slow speeds make public transit a little more attractive to people on a time budget.
This is not necessarily the case - it has been shown that slower car speeds in cities leads to better traffic flows and thus can lead to more efficiency of car travel, less traffic jams. So everyone driving slower can lead to more reliability and less average travel duration of cars.
Both of these can be true.
