I am allergic to shiny things; just because a Google Forms survey on vacation habits has been filled out does not prove much about identity document verification.
Let's strip away the hype: the 78 responses are a superficial observation, not causal evidence for these behaviors, especially when 25% of people wait until the last minute.
What really changes at the cash flow or behavior level?
For example, in Luxembourg, the validity of documents for cross-border workers is a daily legal constraint, not just related to vacations.
