There are two types of car companies in Germany: those on track to switch to fully electric production in the next 5-10 years; and those nowhere near on track that are very afraid of the implosion of their market share as those others are saturating the market with EVs. That's not a future thing; it's already happening.
So, the Germans committing to any ICE phaseout would speed this process up and mess with the (long) time they've given themselves to get out of this mess. The problem with that timeline is that they no longer control it. The transition is happening, whether they like it or not.
Tesla was within a few hundred cars of dethroning the VW Golf as the most popular car in Germany. VWs iconic Wolfsburg plant, which was restored by the allied forces after WW II, is hitting a record low production volume this year at the same time Tesla is opening up a factory in Germany. That's not a coincidence. And VW is one of the better prepared manufacturers. They actually have a decent shot at surviving the transition to EVs. But that's not necessarily true of the other manufacturers.
