Wrong question. The right question is: is the solar panel able to be CO2 neutral (at least) or CO2 negative. We don’t get anything out of it if producing the solar panel costs more CO2 emissions than it saves by producing electricity.

Before you ask: I don’t know the answer. I was looking into this thread in hope to find it.

With all the good arguments against VW you had to pick the dumbest.

Tesla cars are a mixed bag (for Europeans, at least).

The software is good (although it got worse, many things now require multiple touches, which is really bad when driving), and it is better than every other brand I know.

But a lot of other aspects are suboptimal. E.g. the insulation is sub-par, resulting in more noise. The assistance systems are really bad, the car tried to kill me multiple times on the Autobahn. The cameras are bad when it’s dark outside, often I have to guess what I see in the rear camera when parking. The placement of the rear camera leads to dirt on it, I have to clean it every day to be able to use it. Etc, pp.

Nothing is so bad that I would advise against a Tesla, but these are many small paper cuts I was not used to in other brands.

That said: don’t buy a Tesla. Musk is a Nazi. Don’t support Nazis, punch them.

Edit: didn’t notice the train joke. Nice, you got me ;-)
