$10.44 billion
Projected European bike market revenue (2024):

Just imagine if 74% of Luxembourgians decided that their smartphone must have a USB-A port, as an essential requirement. How many major manufacturers would accommodate them instead of continuing to sell "normal" phones? Sure, they could put a USB-A port onto all phones globally sold, but why bother? It's more expensive and nearly nobody outside of Luxembourg would want that feature.
