Just went to West London VW today to put in my order for a new Golf 8, 1.5 eTSI 150 7 speed LIFE DSG. I also asked about the folding mirrors. They assured me that the 2021 version would come with them as standard – and note I’m getting a LIFE, not a STYLE. They agreed that the 2020 models didn’t have them and customers were unhappy and surprised about this – even the salespeople. I even called him back to confirm after finding this forum. Thought I’d update you all in case someone else has the same question. He confirmed that they can fold electronically whilst driving (through width restrictors), and will also fold automatically when you lock the car with the central locking.
