I don’t think they’re saying that no one thought of it, but he’s right as a programmer those edge cases are always pushed out, kicking the can down the road. That doesn’t mean VW isn’t liable - it’s their fault still - they should have been able to help. But we can understand how it happened.
They probably called some guy on the 24/7 help line making minimum wage who will get fired if he ever gave out a free service and probably gets dinged if a call gets escalated. Those processes probably don’t exist. They sure as hell will now.
