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