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