Let's cut through the hype: a Google Forms survey on holiday habits is not enough to prove the reason for identity document checks.
Just because people plan ahead doesn't mean they check their papers for holidays; administrative compliance or significant cash flow are often the real reasons.
The 78 responses are an observation, not a causal proof for these behaviors, especially when 25% wait until the last minute.
In Luxembourg, for example, the validity of documents for cross-border workers is a daily legal constraint, not just a travel quirk.
