Well, if you had checked some facts regarding wealth tax and speed limit, you would have known that both measures are highly inefficient and especially speed limit on the autobahn factually irrelevant regarding almost every aspect you mentioned bar co2 emission, which is such a small amount, that it's almost irrelevant as well (especially considering that the speed limit would hit electric cars as well!!). While I - obviously - never said those two aspects are of priority to me, they are still important. If you ask why, here's my answer. If you don't bother, it's fine.
Both measures are more symbols than efficient tools to make the world a better place. The green party and to a certain extent the SPD as well are known for good theoretical ideologies, but highly impractical approaches to implement actual key aspects in daily life. I, personally, don't like inefficient symbol politics, especially when it comes at the cost of a substantial loss of individual freedom. Now if you think about it, our complete outlook on the world and what our basic rights are and what freedom in a modern society means has been changed by covid. People seem to accept ideological symbol politics dictating and violating their freedom without even thinking. It's not surprising that many former members of the Bundesverfassungsgericht and other experts who are currently not part of our judicial system have deemed many/most of the corona measures as unconstitutional. Thing is, I get why our legal system has not acted in a mechanical way in that regard, in order to maintain control over the situation and because the government needs to have some kind of margin when it comes to unpredictable global crisis situations. But we should be careful about abolishing more and more freedom without conscientously checking the necessity.
Regarding wealth tax, this is a much more debatable matter and might be valid in the future. My concern is though that in this highly globalized world cash cows would start pulling out of germany soon enough if something substantionally happened in that regard (I personally know some people who have already bought real estate overseas because of that). The concrete design of such a tax is the key aspect, though, and I didn't see either the SPD nor the Grüne as competent enough to implement such a costly tool at this moment. Covering up your own wealth has never been so easy as it is at this moment, so in order to actually collect some money, the government needs to dig quite deep in many cases. Which costs absurd amount of money and - having worked for the government myself - I can absolutely assure you that the apparatus is already extremely inefficient. You would never believe it unless you have worked there. So the call for "more state" is something I'm not very fond of. Many of the authorities - especially on the communal level - are basically state financed economic stimulus programs to get their inhabitants to work. It's hard to believe this is happening on a daily basis on a gigantic scale when it comes to the government's work.
Edit:
the funny thing is, the SPD and the Grüne have understood that those two measures are negligible, which kind of shows already that they themselves deemed it not as important as they made it out before the election (just symbols...)
