It really started a fire underneath them that they couldn't just ignore, as most other carmakers, including VW continued to have the ingrained thinking that EVs are just a "fad" or a "niche market" that they need to address "somehow", but mostly not put a lot of effort into it.
Tesla Model 3 having 400,000 pre-orders in week 1 probably freaked out most carmakers, too, though. I'm glad VW, as well as other carmakers have realized by now that EVs are the future of the vast majority of road vehicles, and there is nothing stopping it.
