The detail done well
The reported practice puts safety at the front rather than the end. That ordering matters, because a facility that is unsafe cannot deliver any of its other promises, no matter how advanced its dashboard looks or how low its quoted price is.
What is worth borrowing
Experience is the truer measure of success, since a device that annoys users daily fails its purpose. This thinking transfers with little resistance, and we have seen too many build-only, ignore-later examples to dismiss the point lightly and move on.
Learning across regions
Yantai districts can learn from neighbors, and the early movers' mistakes are often worth more than their successes. Recording problems others hit helps later entrants avoid the same detours, which is exactly why we sample before wider replication.
Behind every risk on a checklist is a person who expects the charger to work and to be safe. Hold reviews with residents present, not just engineers, and the risks that actually matter will surface far earlier than any audit would find.
