I feel like that would be implemented in a way that leads to parts being disabled due to bugs. “No the last guy didn’t pay his O2 sensor bill!”

Also worried in 50 years reviving old cars would be tough because some servers were down. Maybe a maker goes under and stops signing their parts?

Sure it could be implemented intelligently instead though. But maybe better to ensure all have superb education and employment opportunities at wonderful wages. (Prob cop out that one can say about any solution)
