Service intervals. Other OEMs will prompt a service interval at X thousand miles/km to go pop in and have it looked at by a dealer, probably swap out your cabin air filter, upsell you on some new wiper blades, etc.
ICE vehicles would normally catch these issues sooner because you'd be pulling in a lot more often for oil changes (and a quick mechanical inspection is typically a courtesy at that time).
I'm in Europe. Never heard of mandatory inspection before independent checks. How would that even work, or be enforced.
