These could all be researched at the time of purchase though. There's nothing in the daily news about VW or Ukraine that can't be learned more efficiently by doing some research just before purchasing a vehicle or vacation.
There's nothing wrong with keeping tabs on the latest headlines, I personally do so and am fine with it, but there's nothing essential about it either. A person who never reads the news will still find out about something like Covid from a hundred other sources in short order.
