In episode 4 they have some more charging issues, drove through southern Germany, Switzerland and parts of France, and went to a Taycan unveiling.
In episode 5 they made it to Valencia, once they were there they needed to tow the Taycan because they went to the wrong charging station.
In episode 6 they do a summary of the entire trip.
Bjørn Nyland talked about this road trip in one of his most recent videos. He does a good job talking about the charging structure in Europe and has some interesting insight on driving in Europe with EVs.
